啊同学们，不要笑我，我要问这道题，

有45个家庭订三种报纸，其中27个订A，18个订B，12个订C，订A和B的9个，订B和C的8个，订A和C的7个，若三种都订的等于没有订的，而且有6个是没有订的，问只订一个的有多少

27+18+12-2（9-8-7）+3*6＝27

我晕了，彻底晕了，谁给我讲讲呀。我觉得不应该是9-8-7吧，是9+8+7，再就是为什么加3乘以6呢

是的，是加号，我认为是这样27+18+12-（9+8+7）+6＝45-6洁洁MM最好画一个韦恩图比较清楚，当把中间的两部分减去的时候，把重合三次的部分减了3次，就相当于挖空了，要补上去：等于45-6个订了报纸的人

总觉得这个JJ多了个条件，已经告诉6个=没有订的=三种都订的了

继续SOS吧....这条题目是实在看不懂了...

10. 难题: (我唯一不太确定答案的题目)某符号代表一个数学式,(我用$代替). 请问
   X $ Y = Y $ X ?

   (1) X $ 1 = X^2 + X + 1

   (2) X $ Y = X^2 + XY + Y^2 

究竟谁代谁啊???????????????????????????????????????????????????????????????????????????/

只有条件2涉及了X与Y的关系，而且可以互换，而条件1没有X和Y的关系，不知道两个可不可以互换

再问一条

１０. 还有一题，说学spanish的５６％，japanese４０％，spanish里２５％也学japanese，求neither

也是画韦恩图，中间2门都学的是56%*25%，所以都没有学的是1-（56%+40%-56%*25%）

洋洋,北美的考场有哪些注意事项? MBA.COM发的邮件是不是要打出来带去？还是把号码记住就好了?

9. Astronauts who experience weightlessness frequently get motion sickness. The astronauts see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies are not moving. The astronauts’ experience is best explained by the hypothesis that conflicting information received by the brain about the body’s motion causes motion sickness.

 

Which one of the following, if true, provides the strongest additional support for the hypothesis above?

 

A.       During rough voyages ship passengers in cabins providing a view of the water are less likely to get motion sickness than are passengers in cabins providing no view.

B.        Many people who are experienced airplane passengers occasionally get motion sickness.

C.        Some automobile passengers whose inner ears indicate that they are moving and who have a clear view of the objects they are passing get motion sickness.

D.       People who have aisle seats in trains or airplanes are as likely to get motion sickness as are people who have window seats.

E.        Some astronauts do not get motion sickness even after being in orbit for several days.

这道逻辑题太晕了：答案A。不太明白The astronauts see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies are not moving. 想说什么意思。也不明白答案A跟它什么关系
