摘要
对生日问题进行了调研分析,统计调查了5个年级34个班共1484名大学生的生日,验证了"一个班级中至少有两个人的生日相同"这个事件发生的概率确实非常大.为概率统计的实验实践教学改革提供了参考实例.
This paper studies the birthday problem by collecting real data and conducting theoretical analy- sis. A total of 1484 university students＇ birthdays from 34 classes and 5 grades are collected. It shows that the probability of at least two people having the same birthday in class is indeed very large. This provides an example for teaching reformation of experimental practice about Probability and Statistics.
