A carnival game charges $3 to play.  If the person wins, the carnival provides a prize worth $15. If the person loses, the carnival pays nothing.  The carnival estimates that a person only has a 0.11 probability of winning. Use the probability distribution to find the expected earnings for the carnival, given that E(X) = x1p1 + x2p2. (Round to the neares(x) Earrings (x) Probabilities P(x) -$12 0.11 $3 0.89
