Ok, i couldnt resist another puzzle because this is an interesting one in a lot of ways (no more puzzles tomorrow I promise):
You are on a game show and there are three doors. The presenter tells you that behind one of doors there is a car and behind the other two are goats. If you pick the car you win it. After you have picked a door the presenter opens a different door with a goat behind it, he then gives you the chance to change what door you open. What should you do? Stick with your door, or change?
I remember this puzzle from The Curious Incident of the Dog in the Night Time, about the boy with aspergers. In case anyone isnt familiar with it, i wont say what the answer is. But in the book, apparently this question was put to some Indian woman with an absurdly high IQ, she may have been a professor or something, i cant remember. Anyway, she got the answer right.
But because its quite an unintuitive answer, she received shedloads of angry emails, some from other professors I believe, saying she was talking bollocks and they couldnt believe she'd made such an error.
So do you stick with your door, or change?
