In probability theory, the birthday problem or birthday paradox concerns the probability that, in a set of n randomly chosen people, some pair of them will have the same birthday.In a group of 23 people, the probability of a shared birthday exceeds 50%, while a group of 70 has a 99.9% chance of a shared birthday.

The chance that two people in the same room have the same birthday — that is the Birthday Paradox . And according to fancy math, there is a 50.7% chance when there are just 23 people + This is in a hypothetical world. In reality, people aren't born evenly throughout the year, and leap years are excluded. However, the numbers should still be pretty close. More on this in the appendix
Das Problem besteht darin, eine ungefähre Wahrscheinlichkeit zu berechnen, dass in einer Gruppe von n Personen mindestens zwei denselben Geburtstag haben. Der Einfachheit halber werden Abweichungen in der Verteilung wie Schaltjahre , Zwillinge , saisonale Abweichungen oder Abweichungen an Wochentagen nicht berücksichtigt, und es wird angenommen, dass alle 365 möglichen Geburtstage gleich wahrscheinlich sind - Discussing the Birthday Paradox itself and the maths behind it (how many people do you need to have in a group so that there is an over 50% probability of 2 people sharing the same birthday - the answer is 23) - Using the maths of the paradox to calculate how many people you would need for that probability to be 70%, and then 90 Simon Pampena gives his take on THAT viral math problem from Singapore.

The Three Prisoners problem, published in Martin Gardner's Mathematical Games column in Scientific American in 1959 is equivalent to the Monty Hall problem. This problem involves three condemned prisoners, a random one of whom has been secretly chosen to be pardoned. One of the prisoners begs the warden to tell him the name of one of the others to be executed, arguing that this reveals no information about his own fate but increases his chances of being pardoned fro
The usual birthday problem assumes trivial rank-frequency characteristics. We assume every birthday is equally likely. So the fact that we get a counterintuitive answer doesn't have anything to do with rank-frequency / Zipfs law. Rather it has to do with how the pigeonhole principle becomes important rather quickly. This is true with words as much as is is with birthdays... the fact that words have a more interesting distribution than birthdays is unrelated Solution: The way to solve this problem is to look carefully at the question and then work through each statement in turn and see what we can deduce from it. From the question we know that Albert has been told May, June, July or August. Bernard has been told 14, 15, 16, 17, 18, or 19

You know when you sit down for a meal in front of the computer and you just need something new to Here's a well-known birthday problem: How many people need to be in a room before it's likely that two of them share a birthday? If there's 400 people in a room, then there's definitely a birthday match, but if there's 300 it's almost certain as well. What's the smallest crowd so that the probability of a match birthday is over 50%
Who shares a birthday there, obviously the same chance of sharing one, unless, of course, two of the people in that classroom are twins, then the odds are already met, but the odds of a third sharing any one birthday with the twins or with another person go down considerably In probability theory, the birthday problem or birthday paradox concerns the probability that, in a set of n randomly chosen people, some pair of them will have the same birthday. By the pigeonhole principle, the probability reaches 100% when the number of people reaches 367 (since there are only 366 possible birthdays, including February 29). However, 99.9% probability is reached with just 70. The Solution to Albert, Bernard and Cheryl's Birthday Maths Problem. Tweet. Josh Pull. Last Updated: 14 April, 2015. View our 11+ tutors View our A Level tutors View our GCSE tutors View our IGCSE Tutors . The internet has been abuzz with a Maths problem that has everyone stumped. It was set by the Singapore and Asian School Math Olympiads. The question (and solution) are below. Question. The birthday problem is a widely used problem that, similar to the Monty Hall problem, is rather counterintuitive. The question is posed: What is the smallest number of people you need to have in a room before it is more likely than not that two people share a birthday? Many students will answer 182 or 183 because 182.5 is half of 365, which seems correct
The fact that the birthday problem has a value (23) in the same range is pretty much a coincidence. There are many more words than days of the year, so we might expect it to be much higher than $23$, but the fact that each word is not nearly equally likely (i.e. Zipf's law) pushes the value down again The Monty Hall problem is a brain teaser, in the form of a probability puzzle, loosely based on the American television game show Let's Make a Deal and named after its original host, Monty Hall. The problem was originally posed (and solved) in a letter by Steve Selvin to the American Statistician in 1975. It became famous as a question from reader Craig F. Whitaker's letter quoted in Marilyn.

Diving into the Birthday problem with kids. mjlawler Uncategorized October 12, 2019 2 Minutes. Earlier in the week I learned that my older son's high school English class has 24 students and 3 pairs of students who share the same birthday. None are twins, so no tricks or anything like that, just a fun fact for this particular class. I thought it would be fun to figure out how rare something.
