Jerry Falwell was also born on 8/11. This is the first year I will NOT hear that fun fact on my birthday.
There’s a great probability riddle that asks something along the lines of: if you have a class of 30 students, and someone bets you that at least two people share the same birthday, should you take the bet?
Interestingly, the line at which the odds hit 50-50 is 23 people. With 30 people, it’s about a 70% chance. At 60 people, it’s over 99%.
And, the internet being awesome, someone’s done an examination of said riddle: http://noca.leaver.org/birthday/other.html
