为什么c是对的

问题如下：

Which of the following statements about the continuous uniform distribution and the normal distribution is most accurate?

选项：

A.

If X~N(μ,σ), then X/σ~N(0,1)

B.

The cumulative distribution function of the continuous uniform distribution is a curve.

C.

If X is a random variable which is continuously uniform distributed, then P(X=a)=0 (a is a specific value).

解释：

C is correct.

If X~N(μ,σ), then (X-μ)/σ~N(0,1), so A is wrong.

The cumulative distribution function of the continuous uniform distribution is a fully straight line ,so B is wrong.
