Question

一道GRE数学题，Kaplan上的，麻烦大神们帮我看看

there are five employees willing to serve on one of two different committees. If each employees can only serve on one committee, how many possible ways are their for the openings on the committees to be filled?

Answer 1

这个题我当时也理解错了，他说的one committee只能有一个employee，而不是把这五个都分配掉，所以就变成了5*4，但是我觉得题目也没说明白，不知道是不是有默认的美国式理解。回答得应该晚了，楼主应该用不到了。

追问

还好啦，上次数学166，还得再刷一次，苦逼啊
