原始題目，給個ａｎｓｗｅｒ　吧
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?

翻譯:

假設你現在在一個遊戲節目裡, 並且要從三個門裡作一個選擇;
其中一扇門後面是一輛車, 而其他兩扇門後面是羊,
你選擇了一號門, 而知道正確答案的主持人打開了有羊的三號門,
然後主持人對你說:你要不要換成二號門?

換選擇對你會不會比較有利呢?
