How to calculate the birthday problem
Web26 mei 2024 · Let the probability that two people in a room with n have same birthday be P (same). P (Same) can be easily evaluated in terms of P (different) where P (different) is the probability that all of them have different birthday. P (same) = 1 – P (different) P (different) can be written as 1 x (364/365) x (363/365) x (362/365) x …. x (1 – (n-1)/365) WebThe simplest solution is to determine the probability of no matching birthdays and then subtract this probability from 1.
