1)yes
2)not sure因为x为奇数时y,z可一奇数一偶数
偶数时yz全为奇数均是可能情况

这不就是排列组合题么,从六个人里面选两个人采访的可能性有15种,选中的两人恰好是A,B的概率就是1/15
只有A或者B被采访到,责从A,B中选一个人有2种可能性,再从剩下的4人中选1人有4种可能性,总共就是8种,总可能性有15种,所以就是8/15
A,B都没被采访到,责就在剩下4人里选2人,有6种可能性,总可能性有15种,所以是6/15,即2/5

What is the remainder when the two-digit,positive integer x is divided by 3
当两位正整数x被3除时余数是多少?
(1) The sum of the digits of x is 5.(x的数字和为5,则被3除余数为2)
(2) The remainder when x is divided by 9 is 5.(X被9除余5,则被3除余数为2)
A school administrator will assign each student in a group of n students to one of m classrooms.校长分配n个学生到m个班里
If 3 < m < 13 < n,
n个(或3n个,13n个)学生,是否可能每个班分得的学生相同?当然可能了,只需n/m为整数即可.比如m=5 ,n=15
感觉后一题是否描述有问题?或是我理解错了?

很简单啦,表想太难了。
1. x=13.5-(1.5*2)=10.5
2. 这题举特例就可以了。
1) 可以被4整除,那么假设k=20, 题设不成立
2) 4个质数, 那就来1,2,3,5的最小公倍数=30,题设也不成立。
答案是E。你随便举几个数,有不符合题设的,条件就可以排除了...
