【Abstract】 The analytic expression of the distribution function of the binary function of a discrete random variable and a continuous random variable was proposed. The general form of the distribution function of the product quotient and extreme value of discrete and continuous random variables was derived. And the fact that the product and quotient may be a continuous random variable or a singular random variable under different conditions was proved.更多还原
