摘要
采用分布函数法或者公式法能够计算变量分布情况,公式法的计算条件比较复杂,采用分布函数法分析连续型随机变量函数分布问题,讨论连续型和离散型随机变量函数分布的公式,并介绍了基于数形结合法的连续型随机变量函数分布的求解方法。
The distributed function method or formula method can be used to calculate the distribution of variables.The calculation conditions of the formula method are more complex.This paper uses the distribution function method to analyze the function distribution of continuous random variables,and discusses the formula of the function distribution of continuous and discrete random variables.The method for solving the distribution of continuous random variable functions based on the combination of numbers and shapes is introduced.
