    1. I counted 5 vowels out of the 12 letters
    so P(5) = 5/12

    2. prob of anything is a number between 0 and 1
    so 7/6 is a bogus answer
    There is no 0 on a cube, so P(0) = 0

    3. I will assume that there are only these 30 marbles in the barrel
    P(not yellow) = 25/30 = 5/6

    4. green or purple = 10
    prob(green or purple) = 10/30 = 1/3

    5.
    bread: 2
    filling: 4
    condiments: 4
    number of sandwiches possible = 2x4x4 = 32

    you only gave 4 answers for the 5 questions , and struck out on all of them.
