“相互独立事件同时发生的概率”,是高中数学必修课的内容,但我们在教学调查中发现,不少教师在理解“事件的独立性”这一概念时,还存在一些偏差.现分析如下.1概念什么是事件的独立性?课本给出的定义是:事件A(或B)是否发生对事件B(或A)发生的概率没有影响,这样的两个事件叫做相 “Probability of Simultaneous Independent Events” is the content of compulsory math courses in high school, but we found in the teaching survey that many teachers still have some discrepancies in understanding the concept of “event independence.” .1 Concept What is the independence of an event? The text gives the definition of whether the occurrence of event A (or B) has no effect on the probability of occurrence of event B (or A). Such two events are called phase
