Variants edit A common variant of the problem, assumed by several academic authors as the canonical problem, does not make the simplifying assumption that the host must uniformly choose the door to open, but instead that he uses some other strategy.

After choosing a box at random and withdrawing one coin at random that happens to be a gold coin, the question is what is the probability that the other coin is gold.
The fact that these two strategies match (at least 2/3, at most 2/3) proves that they form the minimax solution.

Several discussants of the paper by ( Morgan.
"If the host is required to open a door all the time and offer you a switch, then you should take the switch he said.
In this situation, the following two questions have different answers: What is the probability of winning the car by always switching?
Another way to understand the solution is to consider the two original unchosen doors together ( Adams 1990 ; Devlin 2003, 2005 ; Williams 2004 ; Stibel., 2008 ).You'd rather have a two-in-three shot at the prize than one-in-three, wouldn't you?1, and the host, who knows what's behind the doors, opens another door, say. .The problem is mathematically equivalent to the Three Prisoners Problem described in Martin Gardner 's "Mathematical Games" column in Scientific American in 1959 ( Gardner 1959a ) and the Three Shells Problem described in Gardner's book "Aha Gotcha" ( Gardner 1982 ).Only the Best Slot Machine Games Online Star Trek Slot Machine Play Star Trek Slots Online at Jackpot Party slot machine luglio 23, 2017 uncategorized."Commission, Omission, and Dissonance Reduction: Coping with Regret in the "Monty Hall" Problem"."Monty Fall" or "Ignorant Monty The host does not know what lies behind the doors, and opens one at random that happens not to reveal the car ( Granberg and Brown, 1995:712 ) ( Rosenthal, 2005a ) ( Rosenthal, 2005b ).
