A game of chance involves rolling an unevenly balanced 4-sided die. The probability that a roll comes up 1 is 0.18, the probability that a roll comes up 1 or 2 is 0.41, and the probability that a roll comes up 2 or 3 is 0.49 . If you win the amount that appears on the die, what is your expected winnings? (Note that the die has 4 sides.) Answer = dollars.
