On a T.v. game show a contestant is asked to select a door and then is rewarded with the prize behind the door selected. If the doors can be selected with equal probability what is the expected value of the selection if the three doors behind them have $40000 foreign car, a $3 silly straw, and a $50 math textbook?

How do you start this?
