Let me give you, I'm going to create, q a polar point, I'm going to call it q, and we'll give it some random values.
让我给大家讲解下,我要去创建,一个极坐标点,然后我会去命名它为,然后我给它赋一些随机的值,好,现在我想知道。
You have discrete random variables, like the one I just defined, or there are also--which take on only a finite number of values-- and we have continuous random variables that can take on any number of values along a continuum.
就像刚定义的,是一个离散型随机变量,随机变量还可以有无限种取值,也就是连续型随机变量,随机变量可以取某一区间的一切值
I have it down that there might be an infinite number of possible values for the random variable x.
对于这个随机变量X,可能的取值个数是无限的
