    expected value: - $0.21 loss on 1000 plays: $210.53

    Step-by-step explanation:

    The expected value is the sum of products of payoff and probability of that payoff:

    -$8 (37/38) + $288· (1/38) = $ (-296 + 288) / 38 = - $8/38 ≈ - $0.21

    In 1000 plays, the expected loss is ...

    -$8000/38 ≈ $210.53
