The Monty Hall Problem

I think the people, who are not willing to understand this simple fact, want to keep that type of games on tv, participate there and swap in the end! They want to win the car!

you people who think it doesn't matter are retarded, its such a simple concept, I understood this in second grade and explained it to the class

there is proof, if you search alan davies maths monty hall , user ares213 it shows absolute proof that switching is BEST.
it's from a bbc documentary

Screw probability. You either pick the right one or you don't.

Hello
After seeing this problem explained more clearly on another website I see now that there is 2/3 probability of success on the 2nd choice. It was explained like this. "Imagine someone asking you to draw a card from a deck of cards. The chance of drawing an ace is 4/52. Now if the person removes 1/3 of the cards (17) that are not aces your chances are now 4/35 which are much better than 4/52. You have less possibilities of failures, but the same possiblities of successes.

Do a simulation and report the results.
