Yesterday I saw a nuber of people bet equal amounts of chips on both odd and even at a roulette table, it was then that it dawned on me how stupid some people really are.
I remember from a maths conference they were going through ways 'us mathematicians' can milk average joes for money with a collection of bets that are counter-intuative. Sadly I forgot them all. Does anyone have any? Come on! Let's use our science to treat ourselves once in a while!
