新课改之后,高中教材增加了条件概率这种概型,很多同学在学条件概率时还挺明白的,但学了独立事件概率后,就有点分不清独立事件和条件概率的区别,经常误把独立事件同时发生当成是条件概率,主要谈谈两者的区别。 After the new curriculum reform, high school teaching materials increased the probability of conditional probability. Many of the students learned quite well when they learned the conditional probability. However, after learning the probability of independent events, they could not understand the difference between independent events and conditional probabilities. The simultaneous occurrence of independent events as a conditional probability, mainly to talk about the difference between the two.
