一、教材说明与目的要求: 1、本节从实例出发,说明了互斥事件和n个事件彼此互斥的概念,给出了当事件A、B互斥时计算其和“A+B”的概率的公式;在互斥事件的基础上又讲了对立事件的概念,并介绍了一个简单而有用的公式:尸(A)=1-P(A)或P(A)=1-P(A)。 2、要求学生了解互斥事件与对立事件的概念,以及它们之间的联系和区别,能初步学
First, the teaching material description and purpose requirements: 1, this section starts from the example, illustrates the mutual exclusion of mutually exclusive events and the concept of n events, given when the event A, B mutually exclusive calculation of its “A + B” The formula for probability; on the basis of mutually exclusive events, the concept of opposing events was also introduced, and a simple and useful formula was introduced: Corpse (A) = 1 - P (A) or P (A) = 1 - P (A). 2. Ask students to understand the concept of mutually exclusive events and opposing events, as well as the connections and differences between them.
