excel随机抽样问题 就是现在有八个同学的成绩,抽取其中三个,列出放回和不放回抽样的所有可能性.

excel随机抽样问题 就是现在有八个同学的成绩,抽取其中三个,列出放回和不放回抽样的所有可能性.
要用Excel来做,列出所有抽取的样本啊,什么方法都试过了都没用.
八个同学成绩如下：65、72、77、83、85、88、94、97

抽样放不放回去都是56组. Sub 抽样()Dim Yb(1 To 10000, 1 To 10), Bh(1 To 10, 1 To 10), Gd(1 To 3), A, N, M, X

再问： 哇~~好厉害~~其实我是文科小白一枚。。。。我还以为写一个函数就可以了，没想到要写程序啊。。。不过你好厉害，赞赞。（不知道有没有简单点的解法呢。。。。）
