Although it is close, it is slightly off. there is a 1/366 chance that someone's birthday is the same as yours. So there is a 365/366 chance that someone's birthday is different from yours. If there are 253 combinations, derived from 23 c 2, then there is a (365/366)^253 chance that no pair of those 23 people have the same birthday. (365/366)^253= .5004723662. Which means that the probability that at least one pair have the same birthday = 1- .5004723662. Which gives us about a 49.95276338% Chance.
