不少同学在概率问题解题过程中,经常出错,且不知道错在何处。本文就几个类型概率题的错解,帮助大家分析其原因,减少错解。类型一:“非等可能”与“等可能”的混淆例1.投掷两枚骰子,求所得的点数之和为6的概率.错解:投掷两枚骰子出现的点数之和
Many students often make mistakes in the probabilistic problem solving process, and do not know where they are wrong. This article will help you analyze the causes of misunderstandings of several types of probability questions and reduce misunderstandings. Type 1: Mistakes between “not possible” and “possible” etc. Example 1. The probability of throwing two dice and finding the sum of the number of points obtained is 6. Misunderstanding: The sum of the points where two dices appear.
