CRAZY BIRTHDAY STATISTICS PROBLEM BLEW MY MIND!!!
If you put 23 people in the same room, what is the probability that 2 of them will share a birthday?!? In probability theory, the birthday problem or birthday paradox concerns the probability that, in a set of n randomly chosen people, some pair of them will have the same birthday. 99.9% probability is reached with just 70 people, and 50% probability with 23 people. These conclusions are based on the assumption that each day of the year (excluding February 29) is equally probable for a birthday.
