If the car is behind door 1, the host can open either door 2 or door 3, so the probability that the car is behind door 1 and the host opens door 3 is 1 / 3 × 1 / 2 = 1 / 6 . If the car is behind door 2 – with the player having picked door 1 – the host must open door 3, such the probability that the car is behind door ...
Intransitive dice: One can have three dice, called A, B, and C, such that A is likely to win in a roll against B, B is likely to win in a roll against C, and C is likely to win in a roll against A. Monty Hall problem, also known as the Monty Hall paradox: [2] An unintuitive consequence of conditional probability.
The three prisoners problem appeared in Martin Gardner's "Mathematical Games" column in Scientific American in 1959. [ 1 ] [ 2 ] It is mathematically equivalent to the Monty Hall problem with car and goat replaced respectively with freedom and execution.
Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes–no questions; each question must be put to exactly one god.
Remember this problem is analogous to the Monty Hall problem, and in that problem, Monty knows what is behind each of the three doors; they are already fixed and he can only react to them. If you or someone chooses to condition on who the warden names, this point will be very important to acknowledge. Now the first point.
In the three-card problem, three cards are placed into a hat. One card is red on both sides, one is white on both sides, and one is white on one side and red on the other. If a card pulled from the hat is red on one side, the probability of the other side also being red is 2 / 3 . 53 students participated and were asked what the ...

Marcin Pieprzowski, a QA for The Witcher 3: Wild Hunt, noted that during testing a door that would unlock after a boss was defeated, 12 different scenarios were discovered that would cause the door to not unlock when it was supposed to. Stephan Hövelbrinks noted that many Assassin's Creed games solve the problem by omitting doors entirely. [10]
