WebApr 2, 2016 · Thus the probability that at least one pair shares a birthday for a group of n people is given by. p = 1 − ( 364 365 × 363 365 ⋯ × 365 − ( n − 1) 365) Now you have the probability p as a function of n. If you know the RHS, then you simply find for what value of n we get the closest RHS to p. It so happens that if p = 99.9 %, the n = 70. WebApr 9, 2024 · “RT @NFL_Stats: Happy birthday, CeeDee Lamb!

WebDec 13, 2013 · The birthday problem with 2 people is quite easy because finding the probability of the complementary event "all birthdays distinct" is straightforward. For 3 people, the complementary event includes "all birthdays distinct", "one pair and the rest distinct", "two pairs and the rest distinct", etc. To find the exact value is pretty complicated. WebThe birthday paradox is that a very small number of people, 23, suffices to have a 50--50 chance that two or more of them have the same birthday. This function generalises the calculation to probabilities other than 0.5, numbers of coincident events other than 2, and numbers of classes other than 365.
