    First off Mel is a she :/

    Also I might be wrong but:
    The p(face up) is (50/100) aka 1/3.
    The p(face down) is 100/150) aka 2/3.
    Then it asks for an estimate of it landing face up then face down so we need to multiply the probabilities.
    So 1/3*2/3 which is 2/9. I feel I am wrong though because is asks for an estimate. Anyone else?
