Instead of this single value, a random variable has a function that describes the likelihood of values for the estimate and is called the variable's probability distribution.
取代单个值，随机变量拥有描述估计值可能性的函数，该函数称为变量的概率分布。
Well, the answer is I could put curly d's if I wanted, but I end up with a function of a single variable.
我也可以用∂,但因为是单变量函数的缘故。
In this case, the function may be called with as many arguments as you wish, and those values are collected into a single variable: an array named a: 000.
在本例中，函数可以使用任意数量的参数调用，并且这些值被收集到一个单一变量中：一个名为a： 000的数组。
