Given the date, it seems fitting to begin by mentioning the birthday problem. This is a standard problem given in any introductory probability course, but many people find the result counter intuitive at first.

The birthday problem asks a simple question: . . . → Read More: Math Gets Around: On Birthdays and Trading Cards
