Consider a state lottery that has a weekly television show.
On this show, a contestant receives the opportunity to win $1 million.
The contestant picks from four hidden windows.
Behind each is one of the following: $150,000, $200,000, $1 million, or a "stopper".

Let random variable X be the players gain over 100,000 if he plays.
---
X Values: 50,000, 100,000, 900,000, 0
Probs:::: 1/4, 1/4, 1/4, 1/4
------
E(x) = (1/4)(50,000+ 100,000+ 900,000+ 0) = 262,500
---------
Mathematically speaking, should the contestant take the $100,000?
