Birthday Problem Solution!

Question: If there are 23 number of people in the class what is the probability that you share a birthday with another person in the class?

Answer: In order to solve this we first find the we look at the Number of days in the year = 365

Probability of 2 person having the different Birthday: 365/365 x 364/365 = .997

since the overall probability will be 1, so to find the probablity of to people sharing a birthday will be: 1-.997 = .003


the chances of two people sharing a birthday are very less...

The following Video by Radicaltutor.com explains the birthday Problem in more detail.
