## The Same Birthday

It would be fun for everyone in the class to stand in a line in order of their birthdays. Does anyone have the same birthday as someone else?

Alice in Wonderland learns that in a class of 23 pupils the probability that two have the same birthday is more than a half. Alice is a fictional character created by author and mathemetician Lewis Carroll (1832-1898) but the probability fact is true.

Find more interesting facts like that on the Mathematics Trivia page.
