Birthday paradox 23 people
WebOct 5, 2024 · We know that for m=2, we need n=23 people such that probability of any two of them sharing birthday is 50%. Suppose we have find n, such that probability of m=3 people share birthday is 50%. We will calculate how 3 people out of n doesn’t share a birthday and subtract this probability from 1. All n people have different birthday. In probability theory, the birthday problem asks for the probability that, in a set of n randomly chosen people, at least two will share a birthday.
