NN们，PLEASE stand up and help with JJ organization!!!

I am weak in math that's why I can't help and why I would HIGLY APPRECIATE some help.

I'm taking the GMAT on the 6th ... so PLEASE!!!

Thanks!

不是NN。因为数学不好，自己花费心血复习了很久，也做了两个月JJ。二战数学51，但是verbal惨败。

需要什么帮助呢？讨论题目吗？可以post上来，大家集思广益。

2/14北美，好怕math，哎...JJ好多不会，

34.  (PS) Total 100 students;  33 students speak Spanish ; 25 students speak English ; 22 students speak French ; 11 students speak both Spanish & English; 17 students both speak Spanish & French; 12 students both speak English & French; 9 students speak 3 languages. How many students did not speak 3 languages?

解：100-33-25-22+11+17+12-9=51

 有解释都不怎么明白~

S=4

这题也不明白...有没有讨论帖呢~有CDER说记下就好了，可是我担心碰到变题就麻烦了~

有些JJ的答案是错的,1是JJ主人的答案是错的,2是JJ主人可能漏给了一些条件.我建议还是把JJ都做做,然后看看讨论贴,不懂得再发贴讨论.

我看很多JJ给的很模糊,有些答案被订正,加了一些条件,整理JJ的没有马上更正,所以我建议还是自己好好做,明白为什么.背答案答案实在不太靠谱,因为没有标答.除非一些题大家都讨论了就是这个答案,而这题自己又不会,那就把答案记下来吧.

34,就是画个韦恩图

38，明显少条件，不然算不出。
