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

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

许多随机数生成允许用户指定范围内的随机数字产生。假设您所指定的随机数Y可以采取任何值介于0和2 。然后，由结果产生的密度曲线高度介于0和2 ，在其他点高度为0。
(a）随机变量Y是离散还是连续？为什么呢？
(b）什么是密度曲线的高度介于的0和2 ？绘制图表的密度曲线。
(c)使用图(b)和在概率曲线所在的可能域下求P （元Y <= 1 ）.

System.Random random = new Random(~unchecked((int)DateTime.Now.Ticks));这个没看懂,Random（）函数中的,unchecked((int)DateTime.Now.Ticks)起什么作用? 关于概率统计的题,请给详解 Distribution of minimum of random variables.Let X1 ,X2 ,· · · ,Xn beindependent random variables from an exponential distribution with the density functionf (x) =1/τ* e-x/τ(这里我打不出来,后面是e 统计的英语怎么说 统计用英语怎么说统计动词 AE表达式random（0,360）啥意思 math random * python中random.random()和random.Random()的区别是什么 random spill random是什么意思 random是什么意思?
