Investigation and Analysis of Birthday Problem on the Same Day

摘要：

This paper sums up 1484 university students birthday data of 34 classes of 5 years to verify birthday paradox. Using variance analysis theory we tests that ones birthday distribution is not eqully likely in 365 days of a year, the numbers people bom in the vicinity of October being greater than others, and the numbers born in July being minimum, which increase the probability of same birthday about more than two people in a class. The probabilities of birthday in the same day of unequal possibility and more than two people are studied to explain the necessary law in the accident in our reality livelihood.
