Math Guy: The Birthday Problem
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. However, These conclusions are based on the assumption that each day of the year excluding February 29 is equally probable for a birthday. Actual birth records show that different numbers of people are born on different days. In this case, it can be shown that the number of people required to reach the 50 percent threshold is 23 or fewer.
I'm just curious if anyone has dated someone with the same birthday as them? Not necessarily the same age, just the same day. I wouldn't consider it a deal breaker, but I know some people who would have to have their special day to themselves! The reason I ask, is because I just found out the guy I like shares my birthday, and I'm pretty stunned and laughing right now, as I've never met anyone else who has. Apparently there aren't many July babies where I live.
