Find the least positive integer 'N' so that, in a room containing 'N' people, the odds that two of the people have the same birthday (not the year, just the day) are more than 50%.
[Note: Forget about Leap Year. Assume that a year has 365 days and that people are born randomly throughout the year].

wait, i was wrong. i had this problem before, and i remebered that the class size we had was 26, but we really only needed less, 22 to be exact, to get over 50%
