I'm intruiged. Assuming you don't know my b-day, what would your three guesses for me be?
And the probability is not actually 25%. I'd have to pull out my probability and statistics book to figure it out, but I remember that it was a bit more complicated than just number of tries divided by number of possible answers. I could be remembering something different though. There was something called the binomial ratio that was used to determine the probability of getting a certain poker hand from a deck of cards. Been too long ...
I do remember that the minimum number of people in a room to have a greater than 50% chance of two of them having the same birthday is something like 25 people, a surprisingly low number.
Of course, to verify your 75% number, we would need at least 4 different people to try it on. Yes, I'm a geek.
