那道数学题就是著名的 Monty Hall Dilemma：
The Monty Hall Dilemma was discussed in the popular
"Ask Marylin" question-and-answer column of the Parade magazine.
Details can also be found in the "Power of Logical Thinking"
by Marylin vos Savant, St. Martin's Press, 1996.
Marylin received the following question:
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 number 1, and the host, who knows
what's behind the doors, opens another door, say number 3,
which has a goat. He says to you, "Do you want to pick door
number 2?" Is it to your advantage to switch your choice of
doors?
有三扇门供选择，其中有一扇门的后面是汽车，其它两扇门后面是山羊。主持
人
先让你任意挑选，比如你选中了一号门，这时主持人打开了后面是羊的另一扇门
，例如是三号门。现在主持人问：“为了以较大的概率选中汽车，你是否愿意选
二号门？”。
