Birthday paradox calculation
WebDec 3, 2024 · 1 Answer. The usual form of the Birthday Problem is: How many do you need in a room to have an evens or higher chance that 2 or more share a birthday. The solution is 1 − P ( everybody has a different birthday). Calculating that is straight forward conditional probability but it is a mess. We have our first person. WebJan 29, 2024 · Similarly to the previous case, the conditional probability is simply the probability of n − 1 distinct birthdays in the ordinary 365 -day birthday problem, which is 365Pn − 1 / 365n − 1. So P(A1) = 0.25 365.25( 365 365.25)n − 1 × 365Pn − 1 365n = 0.25 ⋅ 365Pn − 1 365.25n. Therefore the final answer is.
