概率是近年来高考的重点和热点问题.归纳总结概率问题的常见概率模型及求解策略能够帮助学生快速识别题型模式,并有针对性地选择解题方法,准确解决概率问题.本文总结概率问题中的几种常用概率模型,指出其相应的解题策略,供参考.一、选取概型例1某车间甲组有10名工人,其中4名 Probability is the focus and hot issue of the college entrance examination in recent years. Common probabilistic models and solving strategies for summarizing probabilistic problems can help students quickly identify problem type patterns, and select problem solving methods in a targeted manner to accurately solve probabilistic problems. This paper summarizes probability problems. Several commonly used probabilistic models, pointed out their corresponding problem-solving strategies, for reference.
