Lesson 6.11
Bill is playing a game of chance with the following payout. 30% of the time you will lose 20 dollars, 20% of
the time you lose 40 dollars, 10% of the time you win 50 dollars, 40% of the time you win 5 dollars. Find the
expected value of the event and explain if Bill should play this game based on the mathematical expectation.
