    1000 (1/20000) +

    300 (2/20000) +

    10 (20/20000) +

    =

    1800/20000 =.09

    Step-by-step explanation:

    Each ticket purchased is expected to win 9 cents

    Each ticket purchased cost 75 cents

    If you interpret expected winnings per ticket to include the cost then each ticket is expected to lose 66 cents.
