每一个随机试验的整体概率可以用一个相应的随机变量及其概率分布来描述。基于对一维随机变量的理解，采用分布函数法和函数分步法，给出了求二维随机变量概率分布的基本规律。
每一箇隨機試驗的整體概率可以用一箇相應的隨機變量及其概率分佈來描述。基于對一維隨機變量的理解，採用分佈函數法和函數分步法，給齣瞭求二維隨機變量概率分佈的基本規律。

The overall probability of each random test can be used with a corresponding probability distribu-tion of random variables to describe.Based on the understanding of the one-dimensional random variables.This paper uses the method of distribution function and the function of a fractional step method, the basic law pro-vided for two-dimensional random variable probability distribution.The solving method of random variables and their probability distribution of two dimensional, It is the key to learning multidimensional random variables.
