摘要
极限在整个工科数学课程中是一个极其重要的概念,它不仅在高等数学课程中扮演着一个核心角色,而且在概率论与数理统计课程中也有着广泛的应用。此文讨论的正是通过极限在概率论中的应用,从一个求离散型随机变量的条件概率公式,导出一个既可求离散型随机变量的条件概率,也可求连续型随机变量的条件概率的统一公式。
A key role is played for the limit in advanced mathematics, as well as probability and statistics. In this paper, an application of the limit in probability is considered. An unified formula for conditional probability is derived, which can be used to determine the conditional probability of the random of the discrete type and the continuous type.
