Monty Hall problem - Wikipedia, the free encyclopedia. In search of a new car, the player picks a door, say 1. The game host then opens one of the other doors, say 3, to reveal a goat and offers to let the player pick door 2 instead of door 1.

The Monty Hall problem is a brain teaser, in the form of a probability puzzle (Gruber, Krauss and others), loosely based on the American television game show Let's Make a Deal and named after its original host, Monty Hall. The problem was originally posed in a letter by Steve Selvin to the American Statistician in 1. Selvin 1. 97. 5a), (Selvin 1.

It became famous as a question from a reader's letter quoted in Marilyn vos Savant's . You pick a door, say No. Internet Security Scanner Keygen 2013.Rar there. No. He then says to you, . Under the standard assumptions, contestants who switch have a 2/3 chance of winning the car, while contestants who stick to their choice have only a 1/3 chance. The given probabilities depend on specific assumptions about how the host and contestant choose their doors.

A key insight is that, under these standard conditions, there is more information about doors 2 and 3 that was not available at the beginning of the game, when the door 1 was chosen by the player: the host's deliberate action adds value to the door he did not choose to eliminate, but not to the one chosen by the contestant originally. Another insight is that switching doors is a different action than choosing between the two remaining doors at random, as the first action uses the previous information and the latter does not. Other possible behaviors than the one described can reveal different additional information, or none at all, and yield different probabilities. Many readers of vos Savant's column refused to believe switching is beneficial despite her explanation. After the problem appeared in Parade, approximately 1. Ph. Ds, wrote to the magazine, most of them claiming vos Savant was wrong (Tierney 1. Even when given explanations, simulations, and formal mathematical proofs, many people still do not accept that switching is the best strategy (vos Savant 1.

The Monty Hall problem is mathematically closely related to the earlier Three Prisoners problem and to the much older Bertrand's box paradox. The paradox. The problem is mathematically equivalent to the Three Prisoners Problem described in Martin Gardner's .

You pick a door, say No. No. He then says to you, . However, Marilyn vos Savant's solution (vos Savant 1. Whitaker's question implies and both Selvin (1. Savant (1. 99. 1a) explicitly define the role of the host as follows: The host must always open a door that was not picked by the contestant (Mueser and Granberg 1. The host must always open a door to reveal a goat and never the car.

The host must always offer the chance to switch between the originally chosen door and the remaining closed door. When any of these assumptions is varied, it can change the probability of winning by switching doors as detailed in the section below. It is also typically presumed that the car is initially hidden behind a random door and that if the player initially picks the car, then the host's choice of which goat- hiding door to open is random. Selvin (1. 97. 5a)Simple solutions.

The fact that the host subsequently reveals a goat in one of the unchosen doors changes nothing about the initial probability. Another way to understand the solution is to consider the two original unchosen doors together (Adams 1. Devlin 2. 00. 3, 2. Williams 2. 00. 4; Stibel et al., 2. As Cecil Adams puts it (Adams 1. The 2/3 chance of finding the car has not been changed by the opening of one of these doors because Monty, knowing the location of the car, is certain to reveal a goat. So the player's choice after the host opens a door is no different than if the host offered the player the option to switch from their original chosen door to the set of both remaining doors.

The switch in this case clearly gives the player a 2/3 probability of choosing the car. As Keith Devlin says (Devlin 2. I'll help you by using my knowledge of where the prize is to open one of those two doors to show you that it does not hide the prize. You can now take advantage of this additional information. Your choice of door A has a chance of 1 in 3 of being the winner. I have not changed that.

But by eliminating door C, I have shown you that the probability that door B hides the prize is 2 in 3.'. After the player picks a door the host opens 9. On average, in 9.
