看看你是否能和世界上智商最高的人媲美？

这个数学逻辑问题叫“The Monty Hall Problem”

"Suppose you're on a game show, and you're given the choice of three doors. Behind one door is a car, the others, goats. You pick a door, say #1, and the host, who knows what's behind the doors, opens another door, say #3, which has a goat. He says to you: 'Do you want to pick door #2?' Is it to your advantage to switch your choice of doors?"

如果你参加一个游戏有奖节目。 你可以选择三扇门中的一扇。一扇门后面是一辆车，另外两扇门后各有一头羊。你选择了其中一扇门，假设是第一扇门。然后节目主持人——他当然知道那扇门后是什么——打开另一扇门，假设是第三扇门。门后是头羊。然后他问你：“你想重选第二扇门吗？” 如果你重选第二扇门，你赢得那辆车的几率更大吗？
