By choosing a point on the segment that has a certain relationship to other geometric figures, one can usually facilitate the completion of the proof in question. Congruent segments are segments with equal lengths. The segment addition postulate states that if a line segment has three points, then this line segment may be considered two line segments. An example is a line featuring points A, B and C with A and C being the endpoints. In this example, AC = AB + BC. To determine the length of AB, one must subtract BC from AC. Segment Addition Postulate is one of those concepts that is obvious, and yet can confuse students by it simplicity.

The rule of 8’s can be tricky to learn for new occupational therapy practitioners. In some facilities, it takes 15 minutes minimum for a patient to be seen to generate 1 unit. Then there’s some events like evaluations that generate a specific amount of units, e.g., 3 per evaluation.
While you can figure out how many minutes are for 1, 2, 3, 4 units etc. or calculate it by hand, it can be a lot of math if you are trying to get an idea of how you are doing for productivity for the day.
I like to know how I am doing as the day progresses so I can pace myself in the afternoons and plan dynamically as things happen, e.g., patient refusals, patients getting discharged, new admits requiring evaluations, etc. To make my life (and your life) easier, I made a free calculator that can calculate productivity for up to 10 patients.
If you need to see more than 10 patients, you can just sum up the first 10, take note of how many units they all are, and reset the calculator to have 10 more. I’m thinking about adding a field for each patient for you to enter their initials, but not sure how useful that will be or if it will make the screen too cluttered. Let me know what you think.
Hope you all find this handy. Good luck!


Starting in the top left corner of a 2×2 grid, and only being able to move to the right and down, there are exactly 6 routes to the bottom right corner.
How many such routes are there through a 20×20 grid
This has to be the toughest one till now. There are two types of difficult questions. One which you don’t understand at all what to do, I mean they are way out of your reach. There are other questions which you understand but then get quite stuck at it. This question was of second type.
As soon as I read it, I was sure that I don’t have to get into the graphical complexities of it and just consider this as a matrix, give them numbers and make an algorithm which will tell how you reach from point A to point B. So for 2 by 2 matrix , I made :
1 -- 2 -- 3 | | | 4 -- 5 -- 6 | | | 7 -- 8 -- 9
So for this 2 by 2 matrix, there are 6 possible paths (as given in the question) which goes from point 1 to point 9. So there was the first generalization. For a n X n matrix there are going to be (n+1) * (n+1) points.
Now one way to solve this is writing down all the possible paths which it can take from first point to last point. So for this 2 by 2 matrix , all the possible paths are :
1 -> 2 -> 3 -> 6 -> 9
1 -> 2 -> 5 -> 6 -> 9
1 -> 2 -> 5-> 8 -> 9
1 -> 4 -> 5 -> 6 -> 9
1 -> 4 -> 5 -> 8 -> 9
1 -> 4 -> 7 -> 8 -> 9
Few observations :
• For a n X n matrix each path would contain 2n + 1 elements.
• There has to be n rights and n downs always to reach to the destination.
I was sure now, that there is formula to calculate the number of possible paths but it was difficult to arrive to the formula based only on this single matrix. So I decided to follow the same procedure for 3 by 3 matrix as well.
3 X 3 matrix also satisfied the above two observations and the number of possible paths for 3 X 3 matrix came out to be 20. It was not possible to find all the possible paths manually for 20 X 20. So I was trying to find out the formula for number of paths.
2 X 2 6
3 X 3 20
I was thinking about different kinds of generalization like 3 X 2 is 6 and 4 X 5 is 20. Ummm, but that doesn’t make any sense.
Maybe the number of paths in 3 X 3 matrix is 24 and I have missed some of them. So for n X n matrix we can have n + 1 ! paths. So for 2 X 2 is 3! And 3 X 3 is 4! . So when I checked with 21! as answer it showed as wrong answer and hence unfortunately my assumption was wrong. 3 X 3 only has 20 paths and not 24.
I thought about this for 3-4 days in various ways but finally I gave up and googled for a possible solution. As I correctly thought there was a formula to calculate but the formula was a little complicated for me to derive.
The formula was :
(2 X n) ! / n! n!
So for 2 X 2 matrix the answer is :
(2 X 2) ! / 2! 2! = 6
for 3 X 3 matrix it is :
(2 X 3)! / 3! 3! = 20
So finally, I just did the calculation in R 😛
prod(seq(40)) / (prod(seq(20)) * prod(seq(20))) #  137846528820

Calc 1: Blowing up Emerald Forest
At some point after a clash between Alpha and a goon, Emerald Forest gets its shit fucked so let's calc that.
Emerald Forest is about 10 km^2 in area, leaving us with a radius of 1.58113883008419 km.
((1.58113883008419/0.28)^3)/2 = 90.03387106437851 kilotons, Town level+
Calc 2: Blowing up Emerald City
Emerald City is approximately 1980 km^2, giving us a radius of 22.24859546128699 km.
(((22.24859546128699/0.28)^3)/2)/1000 = 250.8439949284133 megatons, Mountain level
So yeah, there you go.
EDIT: I decided to have the Emerald Forest be compared to the size of an actual forest. For this, I'll use the Ocala National Forest in Florida, which is 673 square miles or 1743 square kilometers.
This gives us a radius of 20.874625745148103133692327317502 km.
(((20.874625745148103133692327317502/0.28)^3)/2)/1000 = 207.18199181050213967990232390218 megatons, Mountain level


The Wondertopia WN-102 is as close as Sharp came to a shoot-em-up calculator and was a departure from the first two of the Wondertopia series which had more of a mathematical feel.
Firstly, the WN-100 focused mainly on statistical functionality with coin toss and dice throw probability ‘games’ along with a reflex tester, while the WN-101 was a number-switcher game which required a certain amount of thinking.
With the WN-102, though, it was all about fun. Just like the original space invaders, players had keys for left, right and fire.
The aim was to shoot the two (later three then four etc) invaders before they counted up to 9. Once an invader was shot, it reappeared elsewhere on the display and started counting up slightly faster.
To a generation of kids used to similarly-themed arcade games, this was instantly recognisable and easy (but still challenging) to play.
Although the Wondertopia calculators are very rare these days, the WN-102 is the second most ‘common’ after the WN-100. It didn’t have sound, which it would have benefitted greatly from, although this probably made it easier to play in class without getting caught by the teacher.
Like the other Sharp models, the WN-102 is well-made and holds up well 30+ years later. If you find one of these in the wild, expect the bottom row of graphics to be quite worn since most examples are very well-played.

Climate Dynamics is an advanced undergraduate - level textbook that provides an essential foundation in the physical understanding of the earth's climate system. The book assumes no background in atmospheric or ocean sciences and is appropriate for any science or engineering student who has completed two semesters of calculus and one semester of calculus - based physics.
Describing the climate system based on observations of the mean climate state and its variability, the first section of the book introduces the vocabulary of the field, the dependent variables that characterize the climate system, and the typical approaches taken to display these variables. The second section of the book gives a quantitative understanding of the processes that determine the climate state - radiation, heat balances, and the basics of fluid dynamics. Applications for the atmosphere, ocean, and hydrological cycle are developed in the next section, and the last three chapters of the book directly address global climate change. Throughout, the textbook makes connections between mathematics and physics in order to illustrate the usefulness of mathematics, particularly first - year calculus, for predicting changes in the physical world.


In order to be a favorable champion in the video game of lotto game or at the very least have a minimal development in your lottery game end results, it is vital to discover a method to accomplish this. This does not need you to research a refresher course in an academy or to produce mathematical solutions. Nonetheless, you do require to get crucial study on exactly how to win the lottery 꽁머니 game to discover some essential understanding of which numbers are one of the most possible to strike the pot. In the beginning look, this might appear facility yet after taking advantage of the confirmed methods to comprehend the lotto game, you will certainly have the ability to continually choose the numbers which are extra likely ahead up.
Second, the mathematics specialists and also various other lottery game specialists have actually understood that in real life conditions, what in fact occurs in gaming is the contrary of what a great deal of gamers assume. As an example, you will certainly attain even more revenue if you pick lotto game numbers that have actually been showing up regularly than various other numbers formerly had. For example, if you check out the previous winning numbers, you will certainly observe that a couple of numbers are duplicated greater than the various other numbers.
Exactly how can you be assured that the numbers you select will win? This is possibly one of the most constant inquiry that the majority of lottery game gamers are asking. Allow me present to you one of the most reliable as well as essential ways of choosing the lotto numbers you can play. This is a validated detailed approach on exactly how to win the lotto.
Initially, a beginner in the lotto video game thinks that the lotto game numbers are constantly picked in arbitrary. It is in fact an outright reality that the numbers are chosen randomly nonetheless; a great deal of newbies would certainly assume that the lotto numbers that will certainly probably turned up in future attracts are just the numbers that have actually not been reeled in the past. Undoubtedly, a great deal of people are under the misapprehension that they need to pick numbers that were rarely pulled in the past.
Third, discover the fundamental gaming expressions such as warm numbers, which are specified as the numbers that frequently struck and also he chilly numbers are the numbers that struck the least constant. A lot of the moment, people concentrate on picking the cool numbers and also there is definitely nothing wrong with that said. Based upon some research, there are long times when cool numbers strike on a basic basis.
4th, amongst one of the most amazing truths of lotto is that you can additionally realistically pick the warm numbers rather than the cool numbers. You will certainly obtain even more success contrasted to selecting just the cool numbers. I have no concept just how these bafflingly occur. Nevertheless, lottery game results from the previous attracts have actually validated that selecting the warm numbers is a relatively efficient method to choose your lottery game numbers.
As a result, an excellent technique on exactly how to win the lottery game is required to be particular that you have a high opportunity of winning. You need to obtain a system that makes use of previous fads as well as outcomes, as well as an efficient system to provide you regular revenues.

Clusters are everywhere. In school, students are placed in different grades and classes. In business, employees belong to different departments. How do we decide who goes where? Shared characteristics such as age, subject matter, or skill, tell us who belongs together.
In the same way, data analysts cluster data based on similarities among data points. Though data clustering is more complex than “clustering” students or employees, the goal is the same. Data clusters show which data points are closely related so we can structure, analyze, and understand the dataset better.
But what exactly are data clusters? And how do we create them? This article defines data clusters, provides examples, and explains how we make them.
Note: data clusters are a slightly advanced topic. To cover the basics, I recommend you read our free Intro to Data Analysis eBook if this article is challenging for you.
Data Cluster Definition
Written formally, a data cluster is a subpopulation of a larger dataset in which each data point is closer to the cluster center than to other cluster centers in the dataset — a closeness determined by iteratively minimizing squared distances in a process called cluster analysis.
In addition to the above definition, it’s imperative to keep in mind the following truths about data clusters:
- Data clusters can be complex or simple. A complicated example is a multidimensional group of observations based on a number of continuous or binary variables, or a combination of both. A simple example is a two-dimensional group based on visual closeness between points on a graph. The number of dimensions determined the complexity of the cluster, and thereby the type of cluster analysis needed to determine it.
- Data clusters in a single dataset can vary depending on the type of cluster analysis used to calculate them. The most common type of data cluster is a k-means cluster, which is created by minimizing the euclidian distance between a cluster center (created as a result of the iterative analysis) and the points in the cluster. If you use a different kind of analysis, the clusters will look different. We’ll look at different analyses below, so don’t worry. It’s easier to understand with an example.
- Data clusters will change based on the number of calculation iterations. We use computers to calculate the minimum distance between points and cluster centers. The number of iterations we have the computer run will determine the efficacy of the minimization. However, it’s rare that two iterations produce the same result.
- Data clusters in a two-dimensional spaces appear obvious, so it may seem like the statistical analysis used to obtain them is overkill. However, this is a perception trap. While you can “get away with” visual clusters in simple analyses, you can’t with complicated clusters. Data clusters in multidimensional spaces (i.e those with 4 or more dimensions), are nearly impossible for the human mind to conceptualize, so you need to use statistics. Don’t worry, it’s not hard with Excel. Once you wrap your head around the concept of minimizing distances, you’ll get it. And I’ll show you how it works in Excel so it’s easy to understand.
Data “Clusters” in SQL Databases
It’s important to note that the term “cluster” can also refer to data that are stored close together in a dataset. For example, SQL analysts may refer to a row in a dataset as a data cluster because it groups related data points.
Database engineers often group multiple datasets together for ease of access, and they refer to these as data clusters as well. If you’ve ever seen a data model, you can get a good idea of why data engineers call these clusters. Here’s an example data model:
Data Table A could be considered a cluster. Moreover, each of the data models and the database as a whole could also be considered “clusters.”
In most cases, a “cluster” refers to data points whose values are close together, but you should always keep in mind that professionals in various fields apply the word to their jobs in special ways — such as a database analyst who refers to a row as a cluster.
Data Clusters Example
Imagine you have a pig farm with 15 pigs. You want to cluster them together based on age and weight. This means you want to minimize the distance between each pig to a cluster center. Let’s imagine you have a graph of the pigs’ age and weight that looks like this:
You can already see how some of the points fit closely together. Visually, we can group some of them together, thereby creating data clusters. Here’s the same data with circles around the clusters.
It’s as simple as that. Each circle is an example of a data cluster. Keep in mind, however, that this is a relatively easy example for the following reasons:
- For starters, we only have two dimensions. More complex analysis may have a larger number of dimensions.
- In addition, the number of observations (pigs in our case) is small, making it easy to conceptualize the results. If we had 10,000 pigs, it’s harder to visually determine data clusters.
- Finally, we’re starting and stopping with 4 data clusters. In a more through analysis, we would need to evaluate the optimal number of clusters. The ultimate goal is to minimize distance between points and cluster centers, and there’s always an optimal number of data clusters to do so.
So data clusters are pretty easy, right? We’ve created them visually, and it’s clear. However, we can’t prove this, and if our example was harder, we wouldn’t be able to do it visually. So let’s talk about formal cluster analysis now.
Cluster Analysis: How to Create Data Clusters
To really understand data clusters, we need to know how they’re created: through cluster analysis. Cluster analysis is the process of creating data clusters by minimizing the distance between data points and a reference.
There are several types of cluster analysis:
- Density clustering. Data clusters are determined by how densely related (minimized distance) they are.
- Distribution clustering. Data clusters are determined by the probability that each point it the cluster center.
- Connectivity clustering. Data clusters are determined by initially assuming each data point is a cluster. It then calculates which points are best suited to be cluster centers based on which are closest.
- K-means clustering. Data clusters are determined by minimizing the distance between data points and a predetermined k number of cluster centers.
Each type of analysis has it’s advantages and disadvantages, but in industry the most common and most useful one is k-means clustering. Let’s look at the data clusters in our pig example to understand better.
Most Popular Clustering Analysis: K-Means Clustering Example
K-means clustering uses a presupposed number of clusters, then minimizes the distance of each data point in the whole set to that number of centers. The key concept to understand in k-means clustering is that only the number of cluster centers is predetermined. It’s only when a computer algorithm starts to minimize distances that we find out where those centers are located.
Disclaimer: the below analysis only starts to make sense when you get to the last step, so if it’s not clear until you’ve gone through it entirely.
Let’s look again at our example of the pigs to understand. The going-in number of clusters we’ll look for is 4. Let’s layout the details here:
- In the gray cells we outline the variables we’re testing — age and weight.
- In the orange cells we create empty space that Excel will later solve for in order to minimize the distance between each point and the assumed 4 clusters.
- In blue cells we list our 15 pigs with their age and weight.
- In the green cells we create our distance calculations between each pig and the clusters. You can see from the formula that this distance is euclidian — that is, it’s the square root of the squared distance between the cluster center and the point.
- The numbers you see in green are just placeholders. We haven’t asked Excel to run a calculation on the cluster centers yet, so the values are just the sum of our two variables.
- The reason we square and square root the equation is to get rid of any negative values (a negative * a negative = a positive). Written here, the formula is as follows:
Once you have set up this layout, you need to add a cell that looks for the minimum distance that each point has with regards to each cluster center. We can do this using Excel’s MIN() function. In addition, we want another cell to easily identify which cluster the points belong to once Excel runs its calculation. We can do this using Excel’s MATCH() function. Here’s what these formulas look like:
Now that you’ve set this up, we’re ready to let Excel minimize the distances. To do so, we need to use an Excel add-on called Solver. You can install it using this guide. Solver works by optimizing a target cell by changing a single or range of cells, given a set of constraints.
In the below example, we’ll set the target cell as the sum of the minimum distance cells in line 9. To do so, we’ll tell Excel to modify the orange cluster cells. Let’s assume our only constraint is that the values Solver produced must be less than our largest know variable, which is cell P3: the weight of the pig named Kim.
In addition, you have to tell solver if the optimization will be linear or non-linear. Since euclidian distance is non-linear, we need to use the Evolutionary setting you see in the picture below.
Now hit solve!
Now we have our data clusters. Solver calculated the optimal cluster centers by minimizing the distance between all of the data points and these 4 clusters. Let’s check to see how it worked graphically by creating a new scatter plot:
But wait, there’s a problem here. Two of our 4 clusters are placed as outliers, which is obviously not correct. What’s happened? Excel could not minimize around all of the clusters because the original data points are too close together.
Remember: we decide somewhat arbitrarily how many clusters we want to use at the start of k-means analysis. in this case, it seems like we chose too many. Let’s try the analysis again using only 3 clusters and see if that helps:
We still have an outlying cluster center. We could remove another, but to me, three cluster centers seems reasonable… we’re missing something else here. The range of possible cluster center values is too wide. We’re letting solver choose values for the cluster centers that are outside our range of ages. We need to scope down the value constraints for the age variables to those between the minimum and maximum ages. Likewise, let’s scope down the weight variables to the minimum and maximum values. It looks like this:
Let’s check the output in a new graph. This looks much better:
Now our data clusters look more reasonable. Not surprisingly, they are different from the clusters we created visually at the beginning of the article. To our eyes, the whole core was best as one cluster, but Excel’s solver has determined a better way to organize the clusters, and has better minimized the distances in doing so.
What does this tell us about data clusters?
It’s easy to incorrectly group observations based on visuals and intuition. Some even argue that data clusters are defined as the result of this statistical approach. This would mean that our visual clusters at the beginning of the article is were not data clusters at all — just circles on a graph. To get trustworthy data clusters, we need to perform a statistical analysis.
Other Techniques: Mean-Shift, Density-Based Spatial Clustering, Expectation-Maximization, Agglomerative Hierarchical
K-Means is the most popular type of clustering because it is the most intuitive. However, it’s far from the only technique. Here are four other popular ones:
Mean-Shift Clustering works very much like k-means, but instead of creating values that serve as cluster centers, mean-shifting uses existing data points to serve as cluster centroids.
Density-Based Spatial Clustering
In density-based spatial clustering, each data point is analyzed as a potential cluster center. A distance allowance of Epsilon determines the number of other points labelled within the cluster. If there are enough points, the point becomes a cluster center. The process is repeated for all points until an optimum center is determined. This process then repeats for the whole dataset.
Expectation-Maximization is similar to K-means clustering, except that it adds standard deviation to the calculation on top of averaging. This allows the clusters to take on more dynamic forms instead of following a circular structure.
Agglomerative Hierarchical Clustering
Agglomerative Hierarchical Clustering performs normal clustering using one of the above techniques, then combines determined clusters until the whole data set becomes one “big” cluster. This approach allows the analyst to choose the number of clusters he/she wants based on a the hierarchy of combination – a welcome flexibility for analysis.
Final Note: How Dimensions Impact Data Clusters
In our clustering exercise, we only examined two dimensions: weight and age. However, we could have looked at 5, 10, 20, or more dimensions. This is difficult to understand.
If we introduce more than 3 dimensions, data clusters are no longer a graphical, visual exercise. Instead, they’re abstract by nature. It’s nearly impossible for a human to “visualize” or “imagine” a dynamic in which there are more than the x, y, and z planes, but they exist nevertheless.
A good way to think about 4th and 5th dimensions is to imagine space and color as dimensions on a graph. You have points on the x, y, and z axes. Then imagine that those axes move through space — this would be a 4th dimension. On top of that, imagine that each point is a shade or color — this would be a 5th dimension. Not easy, huh?
Good data clusters are able to provide valuable insights based on a maximum number of variables. The more variables there are at play, the more information we have feeding the analysis. This is why data clusters are only true subsets when they’re based on statistical analysis.

Deterministic and stochastic are two methods of approach in analysis of the system behavior. Clearly there is NO stochastic or deterministic SYSTEM. Example: There is a cube with six different. Chaotic Transitions in Deterministic and Stochastic Dynamical Systems Book Description: The classical Melnikov method provides information on the behavior of deterministic planar systems that may exhibit transitions, i.e. escapes from and captures into preferred regions of phase space.
In this paper we extend the classical SIS epidemic model from a deterministic framework to a stochastic one. We also study the long time behavior of the stochastic system.

Stochastic Systems, 2. Stochastic Diﬀerential Equations (SDE) When we take the ODE (3) and assume that a(t) is not a deterministic parameter but rather a stochastic parameter, we get a stochastic diﬀerential equation (SDE). The stochastic parameter a(t) is given as. Chaos theory is a branch of mathematics focusing on the study of chaos—states of dynamical systems whose apparently-random states of disorder and irregularities are often governed by deterministic laws that are highly sensitive to initial conditions. Chaos theory is an interdisciplinary theory stating that, within the apparent randomness of chaotic complex systems, there are underlying.

Snow College uses ALEKS Placement, Preparation and Learning (ALEKS PPL) Assessment to determine readiness for mathematics courses. ALEKS PPL is a web-based program that uses artificial intelligence to map a student’s strengths and weaknesses. The Placement Assessment is up to 30 questions and generally takes 60-90 minutes to complete. After the Placement Assessment, an individualized Prep and Learning Module is available for students to refresh their knowledge on forgotten topics.
Mathematics is a lens through which we can see and better understand the world. Yet, too often, teachers and textbooks fail to help students connect the mathematics they are learning to their personal lives. In our classrooms we use numerous and varied real world contexts to introduce mathematical concepts. Readers of this blog will help answer for their students the question, “When am I ever going to use this?” We want students to learn the mathematical concepts behind the procedures and discover how to apply quantitative thinking in their daily lives. We hope this blog will provide you the tips and tools to try this approach in your classrooms. Suggested by Kari Arnoldson

I share the same birthdate as my boyfriend, same date but also same year, our births are seperated by merely 5 hours or so. I know that the chances of meeting someone who was born on the same date than me is fairly high and I know a few people with whom I share my birthday although for the little I've read about the birthday paradox, it doesn't take same year into account.
We've argued before about the probabilities and I am still not satisfied. I find the amount of factors to take into account quite vast up to a point, gender and age, availability, probabilities of separation in our region, etc. Is it even possible to calculate the probabilities on something like this?
How would you go about it?
For any one relationship, the odds of sharing the same month and day are approximately 1 in not exactly because of leap year and because births are not exactly evenly spaced within a year. If you add in year, it's probably something like 1 in or most people have relationships with people relatively close in age.
That is, if you had asked, before meeting your current boyfriend "What are the odds that the next man I have a relationship with will be born on same day and year? However, post hoc that is, while in the relationship it's trickier because you would have noticed a lot of other coincidences too: My boyfriend was born the day before me! My boyfriend's mother has the same name as my mother!
Your question got me thinking, and I realized my girlfriend and I also have a strange birthday coincidence.
She was born exactly days before me! And we are also in a successful relationship! So, first of all, the odds of sharing some weird connection with any random person are probably quite high.
Next one should figure out what the chance is of being born in the same year. However, the chances of dating someone from the exact same year are far greater due to a flaw in the educational system where pooling is done by the date of conception. What that exactly boils down to depends on age and month born, but for me it boiled down to more than 0.
Definitely not normal, but then again, coming full circle, you will find something like that for everyone after the fact. The chance that your boyfriend was born the same year as you is actually very high especially given many situations tend to bring people of very similar age together ; it's a very difficult probability to calculate, though, without data.
But P same day should be roughly independent of whether you were born in the same year. So if you had some good estimate of P Same year , you can calculate the overall probability reasonably well. I'd guess that P same year is roughly of the order of 0. According to wikipedia , Thus, a baseline estimate for sharing the same date of birth would be the above statistic divided by two because it captures 2 years for sharing the same year multiplied by the probability of sharing the same birthday:.
As has been noted, both the shared year and shared birthday probabilities could be further refined based on additional information.
When it comes to two people, there are many potential sources of coincidences. Humans are very good at identifying patterns. Within the domain of date of births, you could imagine many possible similarities: same month; same day of month; same star sign; same birthday, different year; some similarity in the numbers such as 2nd of May and 5th of February; dates are some round number apart e. We could in some sense describe our sense to which any of these feel surprising or like a major coincidence.
But of course, when we speak about coincidences there is a much wide domain of search. For example, we could look at similarities in names, employment history, appearance, etc.
The larger you cast the search, the more possible bases there are for finding coincidences. In general, the more you look for them, the more you will see them. This is analogous to the analyst who performs many post-hoc statistical tests without correcting alpha. With enough analyses, the probability of finding a significant pattern gets close to one even when alpha is small. Although the question is about birthdays, the "birthday paradox" isn't really relevant here.
It's about how many random samples you need to take before you expect at least two samples among them to be equal a collision.
Your question is mostly about the probability of two samples being equal. If there were 30 people in your relationship then you'd expect two of them to share a birthday but there aren't 30 people, there are only 2. The odds of having a relationship only have quite a small effect. Enter your birth date and discover what day you were born on and how long you've been alive. In addition, find out your star sign, chinese zodiac sign, celebrities you share your birthday with and your no1 chart song.

Though it happens to me nearly every day, I never know exactly when one will strike. The grocery store? The park? Lying awake in bed at night? I speak, of course, of the dreaded Math Attack.
Most recently, I was standing at the counter at Wendy's, waiting on some cheese fries, when I noticed the automatic change dispenser. Specifically, I noticed that there were three towers of pennies, but only two of each other coin denominations. My mind started whirring: Why were there more sections for pennies? Is it because the pennies are thicker? No, that's not right, nickels are thickest. If you get change back, are you more likely to get pennies than anything else? What is the greatest number of pennies you can get back in a single transaction? Why I am I thinking about this?
My food arrived, and my questions went unanswered, except the last one. I know what, or rather who, is responsible for my constant compulsion to see the world through a math-tinted lens. That would be the Doctor of Math, otherwise known as my father.
In a world of math-haters, I am an anomaly, and my dad is almost entirely to blame. The man does math problems for fun. He recently stopped a game of Farkle to compute the odds of failing to score any points on the first roll (very, very low, in case you are wondering). I am an honorary member of his college's math club, whose t-shirt reads i2- Keepin' it real. Don't get it? Don't worry. You are surely not alone. I hear that other people call their dads to rehash the latest sport scores. I call mine because I learned a new way to do long division. (I'm telling you, the partial quotients method is where it's at.)
The challenge for me now is to figure out how to pass on this love of all things mathematical to my own kids. Sure, they are a bit young, and my son's favorite number is currently eleventeen, but he has a favorite book, so why not a favorite polygon? (I myself am partial to the rhombus.) Fortunately for my children, their Papa will be more than happy to initiate them into the numerical world. It won't be long before they, too, will fall prey to the joy that is a Math Attack.
