Logic FAIL: Monty Hall Problem – GAH!
Now those of you who know me well will know that I love maths, I can spend hours and hours playing around with equations and figures and formulae, however a friend (http://rocko.co.nr/) told me at the weekend about the Monty Hall Problem and this one got me right in the logic chip. My first reaction to this was ‘that can’t be right, it doesn’t make mathematical sense’. It is a very counter intuitive problem and one that has caused much debate over the years if my googling on the subject is anything to go by. The problem for those of you who don’t know it: "Suppose you're on a game show and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the other doors, opens another door, say No. 3, which has a goat. He then says to you, 'Do you want to pick door No. 2?' Is it to your advantage to take the switch?” Ref: http://math.ucsd.edu/~crypto/Monty/montybg.htm
