| 摘 要： | 给出二维随机变量联合分布函数的性质2,性质3和性质4的证明,然后由性质3与性质4证明性质1,最后以反例说明性质4无法由其它性质导出.性质2,性质3和性质4是二维随机变量的联合分布函数的基本性质,性质1是导出性质,不是基本性质.二维随机变量的联合分布函数的基本性质只有三个.

| Abstract: | In the univariate case,the distribution function has three basic rules.As in the bivariate case,it is often concerned that the joint distribution function has four rules.This paper shows that the joint distribution function has just three basic rules. |
