Abstract:

全概率公式是概率论与数理统计教学中的一个重点和难点内容。文中对全概率公式的授课过程进行了全新的教学设计，解释了该公式与古典概率的关系，通过例题讲述了寻找样本空间的划分的方法，最后将全概率公式应用于敏感性问题的调查中。
The total probability formula is a key and difficult content in the teaching of probability theory and mathematical statistics. A new teaching design for the teaching process of the total probability formula is proposed, in which we explain the relationship between the formula and classical probability and tell the method of looking for the division of sample space through examples. Finally, the total probability formula is applied to the investigation of sensitive problems.
