I grew up in a small town, there were 74 (59?) people in my senior class. All my life I knew a girl who had the same birthday as me, we lived blocks apart and our mothers babysat for each other. Since there was already one match, does that make it more or less likely there would be another pair of matching birthdays? I think it doesn't matter, if you remove 2 from 74 you still have a large set of pairs that could match. Was this discussed already? What if you had a group of people who could be 0 - 100 years old, how long before a pair of people had the same year and day? Let's see that be 1 - 36499/36500 * 36498/36500 * 36497/36500 .....I'll check this out at work. Kevin T. Go mainframe! Go mainframe! Go big blue! Compute that number!
