If 2 different representatives are to be selected at random from a group of 10

employees and if p is the probability that both representatives selected will

be women, is p >0.5?
(1)More than 1/2 of the 10 employees are women.
(2)The probability that both representatives selected will be men is less than

1/10.

答案是E。 可是我怎么觉得是D呢。stimulus1和2不能成立么？

只要p大于0.5就可以了嘛，没有说要求出具体数据。

哦，我懂了，这是道组合题，不是排列题吧，呵呵，我前面把两个概念混淆了
谢谢你的耐心解释。
