选项：
A.The number of books a student owns is a discrete random variable.
B.The temperature of Shanghai is a discrete random variable.
C.The number of sunny days next year in Shanghai is a discrete random variable.
解释：
B is correct.
Discrete random variables is the number of possible outcomes can be counted.
temperature is continuous and cannot be counted, therefore it is not a discrete random variable.
sunny days next year 一定是小于等于365的 为什么还是random呢？
