问题
从前100个正整数中选出两个数a和b
Quantity A: the probability that both a and b are even integers
Quantity B: the probability that (a+b) is even integer
选项
A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案
B
解析
偶数=偶数+偶数=奇数+奇数,所以a+b为偶数的概率=a,b同为奇数的概率+a,b同为偶数的概率,因此选择B。
