Solving the distributionofrandomvariable function which is of great significance whether in theory or in application is an important question in probability theory.
求随机变量函数的分布是概率论中的一个重要课题,无论是在理论还是在应用上都有着十分重要的意义。

Instead of this single value, a randomvariable has a function that describes the likelihood of values for the estimate and is called the variable's probability distribution.
取代单个值,随机变量拥有描述估计值可能性的函数,该函数称为变量的概率分布。
