120集合{r,s,t,u,w}, 问这个集合有多少个不含t 的子集。
                

15(c1,4+c2,4+c3,4+c1,4)

我觉得应该是16

2^4  初中知识,包括空集??

今天去看考场，只有一个小小的紧锁的门，门上挂了皮而森的牌子～～里面的环境没有看到．．．我觉得一个考场里人应该不会太多．．．．

是2^n

解释:

将每一个元素在几个里面的存在状态变成离散状态
这样就有两种状态就是0或1
那么只要将它作为二进制的数进行递增就可以不重复而且完全的得到所有状态
所以每一个元素的两种状态，有N个元素存在
就可以得到所有的状态数是2的N次方
对应的子集就有2^N的不同的子集（包括空集和全集）

补充一下. A 的话是. companies may be partners. when? the next day. what kind of companies? companies that competes one day.

所以画上等号的只是 companies & partners. the next day 点出时间

competes one day 点出哪种companies..

现在你再回去看choice B

companies one day may be partners the next---> 对称是对到家. 但意思错了.

你的身体好些了吧？

大哥能把原句贴出来吗? 通常原句有点小小不同. 我想看ETS这题改了些什么.
