解题方法
9 . 设![](https://staticzujuan.xkw.com/quesimg/Upload/formula/0f4d1249a24300ebfc3d0219f5bb4d06.png)
是由
组成的
行
列的数表(每个数恰好出现一次),
且
.若存在
,
,使得
既是第
行中的最大值,也是第
列中的最小值,则称数表
为一个“
数表”
为数表
的一个“
值”,对任意给定的
,所有“
数表”构成的集合记作
.
(1)判断下列数表是否是“
数表”.若是,写出它的一个“
值”;
,![](https://staticzujuan.xkw.com/quesimg/Upload/formula/9578b9d3e9f25d56b3cff92c362b7b9a.png)
(2)求证:若数表
是“
数表”,则
的“
值”是唯一的;
(3)在
中随机选取一个数表
,记
的“
值”为
,求
的数学期望
.
