文氏图在概率论学习中的妙用

Applications of the Wen-Shi Diagrams to Probablity Theory

目前,在各类大专院校中,概率统计这门课已成为越来越多的专业的必修课,由于概率论的方法有其独特之处,初学者往往感到它的基本概念和公式定理难懂,习题难做.但如果借助图形,便能化抽象为直观,化难为易.

At present ,in each college , the course of Probability and Statistics has been become compulsory course among more and more majors.Therefore . As a result of the special methods of probability , the beginners always find it hard to understand its basic conception , for mulae as well as theorem . Besides , exercises are difficult for to them to deal with . But with the help of the diagrams, the abstract can be turned into intuition.
