The Monty Hall Problem
Look at the math behind the Monty Hall problem with Lisa Goldberg, an adjunct professor in the Department of Statistics at University of California, Berkeley. She helps you understand the probability behind why you should switch doors. You can find this and other great videos at the website “Numberphile”.
