由于概率问题中的有关概念具有一定的抽象性与相似性,故而在求解概率问题时,容易出错,本文就此问题易犯的错误作一归纳总结．一、“古典概型”理解不透彻导致错解古典概型中,利用概率的计算公式P=m/n,应注意:基本事件总数n及要求概率的事件所含基本事件m,一定要在同一试验状态下进行,并且基本事件的计算不能重复或遗漏。
Because the related concepts in the probabilistic problem have certain abstractness and similarity, it is easy to make mistakes when solving the probabilistic problem. This paper summarizes the susceptibility mistakes of this problem. I. Imperfect understanding of the “classical model” leads to the misunderstanding of the classical probability model. The formula for calculating the probability of use is P=m/n. It should be noted that the total number of basic events n and the event that requires probability contain the basic event m, must be Under the same test state, and the calculation of the basic events cannot be repeated or omitted.
