概率论与数理统计中的几个注记
Several Notes on Probability Theory and Mathematical Statistics
摘要: 本文针对学生在学习概率论与数理统计中出现的问题，对随机变量的数字特征、不相关与独立的关系、事件发生与概率的关系以及小概率事件的实际不可能性原理进行了整理，并通过实例进行说明。
Abstract: This paper addresses common issues encountered by students in learning probability theory and mathematical statistics. It systematically organizes key concepts such as the numerical characteristics of random variables, the relationship between uncorrelatedness and independence, the connection between events and probabilities, and the practical impossibility principle of small-probability events. These points are further illustrated with concrete examples.
