Birthday paradox 23 people
WebOut of 100,000 simulations of 23 people, there was a matching birthday in that group 50955 times. This means that 23 people have a 50.95 % chance of having a matching birthday in their group.

WebJun 18, 2014 · Let us view the problem as this: Experiment: there are 23 people, each one is choosing 1 day for his birthday, and trying not to choose it so that it's same as others. So the 1st person will easily choose any day according to his choice. This leaves 364 days to the second person, so the second person will choose such day with probability 364/365.

WebDec 13, 2013 · Then this approximation gives ( F ( 2)) 365 ≈ 0.3600 , and therefore the probability of three or more people all with the same birthday is approximately 0.6400. Wolfram Alpha gives the probability as 0.6459 . Contrast this with the accepted answer, which estimates the probability at 0.7029. WebTo expand on this idea, it is worth pondering on Von Mises' birthday paradox. Due to probability, sometimes an event is more likely to occur than we believe it to. In this case, if you survey a random group of just 23 people, there is actually about a 50-50 chance that two of them will have the same birthday. This is known as the birthday paradox.
