Winning the Lottery, An Expected Value Mystery
- Activity Description
- Topics Covered
- Session Styles
- Mathematical Practices
In 2005, while researching the expected value for lottery tickets in various states, a group of MIT students won millions of dollars in the Massachusetts $2 Cash Winfall drawing. Do you want to know how they did it? This teacher led activity starts with a lottery, explores expected value, and finally ties into finite projective geometries.
