Monty hall. Is this a Monty Python reference? Or something related to a skit of theirs'? --Commarchinin (talk) 04:18, 25 October 2013 (UTC)

Not a Monthy Python -- Monty Hall is a game host famous for Let's Make a Deal which gave birth to the Monty Hall Problem Spongebog (talk)

I don't understand "It is known that door 3 has a goat, but nothing else." What do you mean by that? At the beginning in the Monty Hall problem, a contestant knows nothing. --209.51.184.11 04:27, 25 October 2013 (UTC)

See Monty Hall Problem Spongebog (talk)

It goes like this: Player chooses door A, Monty then opens a door he knows there is a goat behind. Player is then offered a chance to switch.

If you do not switch you get a 1/3rd chance of winning because it was a 1 in 3 guess and nothing changed. But if you take into account that Monty will ALWAYS open a goat door and never a car door you can recalculate the odds. So you have a 1/3rd chance that you initially chose the car which means you will lose if you switch 1/3rd of the time, but you had a 2/3rd chance of not selecting the car initially meaning you have a 2/3rds chance if you switch at winning the car. 184.66.160.91 04:58, 25 October 2013 (UTC)

Reminds me a bit of 1134: Goats make sense. Goats are fine. --132.230.1.28 08:39, 25 October 2013 (UTC)

It's either A or C. Then the player should choose again between A or C. Xhfz (talk) 14:56, 25 October 2013 (UTC)
Sequence of the events (assuming Beret Guy initially selects door A)
Monty: Pick a door.
Beret Guy: I choose A.
Monty: I will open another door. It is B. (He opens it and they see a goat). Do you want to switch doors? (Meaning if he will switch from A to C.)
Beret Guy: I choose door B.
Beret Guy (to the goat): ...And my yard has so much grass, and I'll teach you tricks, and...
A few minutes later, the goat from behind door C drives away in the car that was behind door A.
