标题[计量] 一题计量请教
时间Wed Jul 13 22:11:04 2016
A table of data had 36 entries arranged in 9 rows and 4 columns. A computer
program randomly deleted exactly one entry in each row. If the column had the
greatest number of entries deleted, what is the least number of entries that
could have been deleted in that column?
(A) 2
(B) 3 (C) 4 (D) 5 (E) 6
我对题目的理解如下图
---------------------
| | | | |
--------------------- 9x4的阵列 随机砍掉每列的其中一格
| | | | |
--------------------- if the column had the greatest number of entries
| | | | |
--------------------- deleted: 这个greatest number就是9
| | | | |
--------------------- 因为一栏最多只有九列
| | | | |
--------------------- 但是the least number of entries that could have been
| | | | |
--------------------- deleted in that column就不懂了
| | | | |
--------------------- 原本最多可以砍掉9格 怎麽又问最少可以砍几格????
| | | | |
--------------------- 请问这题该如何翻译呢?谢谢

1F：推 owlrex : 1.电脑随机在每一row砍掉一个数字 07/13 23:31
2F：→ owlrex : 2.然後再砍掉剩下最多数字的column 07/13 23:32
3F：→ owlrex : 更正 2.是砍掉"被砍掉最多数字的cloumn" 07/13 23:34
4F：→ owlrex : 四个column总共被砍九个数字 最平均的分法是(3,2,2, 07/13 23:36
5F：→ owlrex : 2)这个集合 07/13 23:36
6F：推 owlrex : 我不知道刚在推什麽 请无视这段推文XD 07/13 23:50
