考試要求的是符合題意的答案,
但是當你在像其他人解釋題目時,重要的是前因後果,
你不能忽略任何的解釋,
這個題目是可以有兩種問法,
一種是[換不換]
另一種是[玩不玩]這個遊戲,
因為如果這是賭博遊戲,大獎換成獎金,
這時你所重視的將會是期望值是否大於賭金,
這就是事情的一體兩面

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?
