Monty Hall Problem...take 2.

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 number 1, and the host, who knows what's behind the doors, opens another door, say number 3, which has a goat. He says to you, "Do you want to pick door number 2?" Is it to your advantage to switch your choice of doors?

Note: The host will always show you a goat, regardless of your initial pick.

I know how it works. But you just showed that sticking to your door gives you a chance of 1/3. Wich is the obvous part of the story and not the core of the problem. Then you say if you don't get it by now i'm an ideot... that seenes kinda odd...

Well perhaps hab to explain it so often that you lost track a bit ;)

@ComplainBear I'm going to go out on a limb here and guess that English isn't your first language.

@matt02sim I switched 100 times and I stayed 100 times. When I switched, I won 55 times. When I stayed, I got a boner.

The reason is because, the chances that you got the car on the first pick is 1/3, while the chances you got a goat is 2/3. When you switch, you get the opposite of the thing you picked.

Hahaha, oh Man! Hey lets just put it this way:

Two questions:

1. Is there a bigger chance the prize is behind the door one has picked or behind one of the other two doors? Good.

Now:

2. Behind which one of those two? (perhaps the one with the goat, hmm?)

[britionn]

In 50 games I played I won 25 times and 100 games I played I won 51 times.

[Soulgotha]

In 50 games in which I switched, I won 40 times.

[matt02sim]

you are so wrong i did it 200 times and won 199 the one i lost i spilled my milk. so thats why that why if you stay u will win ever time this guy is a goofball.
