NO.PZ2015120604000173 问题如下 Whiof the following statements about the continuous uniform stribution anthe normstribution is most accurate? A.If X~N(μ,σ), then X/σ~N(0,1) B.The cumulative stribution function of the continuous uniform stribution is a curve. C.If X is a ranm variable whiis continuously uniform stribute then P(X=a)=0 (a is a specific value). C is correct.If X~N(μ,σ), then (X-μ)/σ~N(0,1), so A is wrong.The cumulative stribution function of the continuous uniform stribution is a fully straight line ,so B is wrong. 为什么c是对的
B，continuous uniform stribution密度函数图像是一条直线，但累积概率的图像究竟是什么样子呢？为什么还是一条直线？
A是啥意思呢？
请问 讲义里 P（X小于a 或 大于=o 吗
