User:Martin Hogbin/MHP - Not the original choice

Please look at the explanation below, try to understand it then respond as requested in the 'What did you think' section.

Brief reminder of the problem

edit

Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?

For more detail and clarification go back to the problem.

Explanation

edit

An intuitive explanation is to reason that a player whose strategy is to switch loses if and only if the player initially picks the car, which happens with probability 1/3, so switching must win with probability 2/3 (Carlton 2005).
