The Monty Hall Problem is a famous (or rather infamous) probability puzzle. Ron Clarke takes you through the puzzle and explains the counter-intuitive answer.

You can read more about this problem, and the controversy, on Marilyn Vos Savant's website www.marilynvossavant.com

  • My eyes are hurting for reading these stupid ass comments. Think of the problem this way:

    You have a 1000 glasses of water in front of you. In 999 of them there is a drop of poison that will kill you. Only one glass doesn't. Now you have to choose one glass and you want to get it right. I think we can agree that it's almost impossible to pick the safe one. Now I'll remove 998 poison glasses and you're left with the one you picked and the other one I left you with. What do? Of corse you'll swap.

  • That car is lame! I WANT A GOAT!

  • Goats are my friends!!

  • i agree but real life is not mathematics.... any door can have anything

  • That would be amazing, you pick one door with a 1 % chance of hiding the car, but would always end up with a 50 % chance of winning it. No wonder this show never got aired, they would run out of cars in no time!

  • @passwordforgetter: Let's say it's 100 doors, 99 with a goat behind it and one with a car behind it. You picked one door and the host opened 98 other doors, revealing only goats. Would you still think there's a 50/50 chance you choose the door with the car behind it? Remember, this would happen with every contestant every time.

  • Its True...

  • @passwordforgetter You are an uneducated in mathematics, this is an example little bit of variable probability and can be simulated time and time again and shown to be true. Don't trip on concepts you don't fully understand

  • that's really cool lol, never would have thought about it like that

  • @passwordforgetter this video is perfectly logical

  • booby prizes
