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.
