The host can always open a door revealing a goat and (in the standard interpretation of the problem) the probability that the car is behind the initially chosen door does not change, but it is not because of the former that the latter is true. But, these two probabilities are the same. , therefore switching always brings an advantage. SavantriaSavantria [49][13] In accordance with this, most sources in the field of probability calculate the conditional probabilities that the car is behind door 1 and door 2 to be 1/3 and 2/3 respectively given the contestant initially picks door 1 and the host opens door 3. Going back to Nalebuff,[55] the Monty Hall problem is also much studied in the literature on game theory and decision theory, and also some popular solutions correspond to this point of view. [38] This shows that the chance that the car is behind door 1, given that the player initially chose this door and given that the host opened door 3, is 1/3, and it follows that the chance that the car is behind door 2, given that the player initially chose door 1 and the host opened door 3, is 2/3. It is also typically presumed that the car is initially hidden randomly behind the doors and that, if the player initially picks the car, then the host's choice of which goat-hiding door to open is random. Many readers of vos Savant's column refused to believe switching is beneficial and rejected her explanation.

[21][4][24] However, Krauss and Wang argue that people make the standard assumptions even if they are not explicitly stated. Marilyn vos Savant's humility.

Dominance is a strong reason to seek for a solution among always-switching strategies, under fairly general assumptions on the environment in which the contestant is making decisions. According to Bayes' rule, the posterior odds on the location of the car, given that the host opens door 3, are equal to the prior odds multiplied by the Bayes factor or likelihood, which is, by definition, the probability of the new piece of information (host opens door 3) under each of the hypotheses considered (location of the car). [15], Savant sees IQ tests as measurements of a variety of mental abilities and thinks intelligence entails so many factors that "attempts to measure it are useless". The short answer is that your initial odds of winning with door #1 () dont change simply because the host reveals a goat behind door #3; instead, Halls action increases the odds to that youll win by switching.

Later in their response to Hogbin and Nijdam,[45] they did agree that it was natural to suppose that the host chooses a door to open completely at random, when he does have a choice, and hence that the conditional probability of winning by switching (i.e., conditional given the situation the player is in when he has to make his choice) has the same value, 2/3, as the unconditional probability of winning by switching (i.e., averaged over all possible situations). This probability does not change after the host reveals a goat behind one of the unchosen doors. Vos Savant commented that, though some confusion was caused by some readers' not realizing they were supposed to assume that the host must always reveal a goat, almost all her numerous correspondents had correctly understood the problem assumptions, and were still initially convinced that vos Savant's answer ("switch") was wrong.
