    Answer

    $0.1346

    Explanation:

    Find probability of each card and the value of each card and then add them together.

    Probability of getting a heart = 13/52

    Price of one heart =$0.30

    Pay for one heart = 13/52×0.30=$0.075

    Probability of getting a queen =4/52

    Price of one queen =$0.55

    Pay for one queen =4/52×$0.55=$0.0423

    Probability of getting a queen of hearts =1/52

    Price of one queen =$0.90

    Pay for one queen =1/52×$0.90=$0.0173

    Therefore the pay for one draw= $0.075+$0.0423+$0.0173=$0.1346
