c. Interpret the expected value.
This is the most likely amount of money you will win.
O If you play many games you will likely lose on average very close to $0.33 per game.
O You will win this much if you play a game.
d. Based on the expected value, should you play this game?
O No, this is a gambling game and it is always a bad idea to gamble.
O Yes, since the expected value is positive, you would be very likely to come home with more money if
you played many games.
O Yes, because you can win $15.00 which is greater than the $10.00 that you can lose.
O Yes, since the expected value is 0, you would be very likely to come very close to breaking even if
you played many games, so you might as well have fun at no cost.
O No, since the expected value is negative, you would be very likely to come home with less money if
you played many games.
