PROBLEM #2
Suppose you play a game in which a fair 6 sided die is rolled once. If the outcome of the roll (the number of dots on the side facing upward) is less than or equal to 4, you are paid as many dollars as the number you have rolled. Otherwise, you lose as many dollars as the number you have rolled.
Let X be the profit from the game (or the amount of money won or lost per roll). Negative profit corresponds to lost money.
