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.
