目前概率统计的教材绝大多数都以正面陈述的证明为主体。概率统计的概念和命题比较抽象,学生不好理解,而运用反例对概率统计教学有很大帮助。本文给出随机变量和分布中若干命题反例的构造。
目前概率統計的教材絕大多數都以正麵陳述的證明為主體。概率統計的概唸和命題比較抽象,學生不好理解,而運用反例對概率統計教學有很大幫助。本文給齣隨機變量和分佈中若榦命題反例的構造。

Currently, most of probability statistics materials take the proofs which based on positive statement as a main body. The concepts and propositions in. probability statistics are abstract, and they are difficult for students to understand. However, the use of counterexamples plays an important role in probability statistics teaching. In this paper, the construction of random variables and some counterexamples of propositions in distribution are given.
