转化思想是数学解题中的一种基本思想,可以渗透到中学数学的各个问题之中,使所研究的复杂问题转化为易理解的问题,或使研究所需复杂思维转变成便于思考的方式,突出数学本质,从而找到突破问题的方法.用转化思想求解概率问题,会为求解概率问题另辟蹊径,找到巧妙的方法,起到事半功倍的效果.本文就将计数与概率问题转化成几何模型、概率
Transformational thinking is a basic idea in mathematical problem solving, which can penetrate into various problems in secondary school mathematics, transform the complex problems studied into easy-to-understand problems, or transform the complex thinking required by the research into a thinking mode , Highlighting the nature of mathematics in order to find a way to break through the problem.To solve the problem of probability using transformation thinking, will find another way to solve the problem of probability, to find clever ways to play a multiplier effect.This paper will count and probability problems into geometric model, the probability
