统计题（英语）,
Many random number generators allow users to specify the range of the random numbers to be produced.Supposed that you specify that the random number Y can take any value between 0 and 2.Then the density curve of the outcome has constant height between 0 and 2,and height 0 elsewhere.
(a) Is the random variable Y discrete or continuous?Why?
(b) What is the height of the density curve between 0 and Draw a graph of the density curve.
(c) Use your graph from (b) and the fact that the probability is area under the curve to find P(Y
英文我能看懂——！

这不就是均匀分布么.
连续的,why,用定义解释.因为连续随机变量的定义就是一切可能取值充满区间（a,b）,在这个区间内有无穷不可列个实数.
密度函数p(y)=1/2就是height,图就是在y属于（0,2）时候density是一条直线,y在区域外时都是0.
P（Y
