二项分布在试题库随机组卷中的应用

Binomial Distribution Applied in the Stochastic Selection on the Examination Paper Base Management System

介绍一种根据离散型随机变量的二项分布建立试题库随机选题数学模型的方法 ,然后利用此模型实现随机组卷。

In this paper,Introduce a method to establish a mathematic model about stochastic selection on the examination paper base management system and the method is based up on dispersed stochastic binomial distribution,and use this model to come true the stochastic selection on the examination paper base management system.
