英语智力题

There are 4 men:A,B,C,D.Each has a son.The four sons are asked to enter a dark room.Then A,B,C and D enter the dark room,and rach of them walks out with just none child.If one them comes with his own son,in how many ways can this happen?

Answer 1

如果我理解正确，题目的意思 是 ：有4个男人，每个男人都有一个儿子。这4个儿子被要求走进一间漆黑的房间。然后这4个父亲走进房间，每人带一个孩子出来，他们把自己的儿子带出来的几率是多少？

那么这就是一个数学问题，而不是智力问题。。

这个几率是25%
