While playing around in the casino, some weird guy walks up to you. In a deep voice, he says, "Let's Make a Deal!" Immediately, the entire background shifts like a movie set and you find yourself in a game show. Your mysterious "game host" shows you 3 doors (A, B & C) and asks you to choose. Behind one is a car, and behind the other two are goats.
You choose door A. He then opens door C, revealing a goat behind it. (Note: The Host always opens a goat door). He then gives you the option to stick with your original door A, or switch to door B.
Which choice will give you the best odds of winning the car?
