Suppose that you and a friend are playing cards and decide to make a bet. If your friend draws three face cards, where a face card is a Jack, a Queen, or a King, in succession from a standard deck of 52 cards without replacement, you give him $40. Otherwise, he pays you $10. If the same bet was made 15 times, how much would you expect to win or lose? Round your answer to the nearest cent, if necessary.
