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 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 switch your choice?
Do any of you have any noteworthy experiences where knowledge of math helped you in an unusual way?

Are you REALLY any closer to knowing if you should switch?
Yeah, but your numbers are too small or percentages are too large making it look weird.
Assume it scales. Scale this to a billion doors. You pick a door which almost certainly isn't it. Dude opens a B-2 doors leaving a winner and a loser. The loser is almost certainly the one you picked, the winner is the remaining unopened door.
