文氏图在条件概率教学中的应用

Venn Diagram In The Calculation of Conditional Probability

条件概率是概率论的重要概念之一,也是概率统计教学中的一个难点,其关键是找到事件样本空间的一个划分,该文提出采用文氏图进行分析的方法,使样本空间的划分更直观、更易于分析,从而使复杂的条件概率概念的教与学得到有效解决。

Conditional probability is an important concept in probability theory, probability and statistics teaching is a difficult, the key is to find a partition of the event sample space, this paper uses Venn diagrams to analyze ways in which the division of the sample space is more intuitive, easier analysis. So that the complexity of the concept of condi- tional probability of teaching and learning be effectively addressed.
