There are three doors. Behind one door is a car. Behind each of the other two doors is a donkey. As a contestant, you are asked to select a door, with the idea that you will receive the prize that is behind that door. The game host knows what is behind each door. After you select a door, the host opens one of the remaining doors that has a donkey behind it. Note that no matter which door you select, at least one of the remaining doors has a donkey behind it for the host to open. The host then gives you the following two options:
