一、案例背景本节的教学内容是“相互独立事件同时发生的概率”.通过本节课的学习,让学生感受概率的实际意义,提炼相关概念,培养数学能力,解决实际问题.本节的重点是领会相互独立事件同时发生的含义,掌握其概率的计算方法.难点是对事件相互独立性的判定.本节课主体为某重点校高 First, the case background The teaching content of this section is “the probability that mutually independent events occur at the same time.” Through the study of this lesson, let students feel the actual meaning of the probability, refine related concepts, develop mathematical ability, and solve practical problems. The key point is to understand the meaning of the simultaneous occurrence of independent events and to master the calculation methods of their probabilities. The difficulty lies in the determination of the independence of events. The subject of this lesson is a key school
