A little logic puzzle to start your weekend
This is called the "Monty Hall problem":
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?

Only if you do and you win the grand prize. Me? I'd rather have the goat instead of the car. Cheaper on taxes and it will keep the grass cut.
No one wants to take a crack at this?
I'll post the answer a bit later today.
You up your odds to 2/3 if you switch.
Yeah, nice Brad. Way to prove you're so smart when we've already discussed this puzzle offline with Greg. :P
But yeah, Brad's got the right answer.
Loser. ;)
Hey, I'm sure *everybody* out there recognized this as the "Monty Hall" problem. It's on wikipedia!
