| Abstract: | The overall probability of each random test can be used with a corresponding probability distribution 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 provided 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. |
