While we are on the subject of probability and the tendency to ascribe supernatural causes to events, I thought I’d pose another problem for everyone.
You go to a party and there are seventy people there, none of whom you know personally. You get into a conversation with someone and find out that the person has the exact same birthday as you! You are completely shocked and think that some supernatural power has placed you in this position. You also think that the two of you were destined to meet.
So the question I have for you is: What is the probability that 2 people in a group of 70 have the same birthday?
This time the person who gives me the correct answer gets a Gmail invitation, not that they are worth anything now.
Oh and please resist from googling the answer. Well you could, but then it wouldn’t be as much of a fun exercise for you, would it?

1 - [365 C 70]/(365^70)

I know the right answer now… but I realized the mistake after googling for it. So, let me not spoil the fun anymore.
