Answer:
1/15
Step-by-step explanation:
5+3+2 = 10
Chance of pulling out a yellow marble = 3/10
Once you pull out the marble there are 9 marbles left, 2 yellows, 2 blacks and 5 whites.
Chance of then pulling out a black marble = 2/9
3/10 x 2/9 = 6/90
6/90 = 1/15
0 is the answer because if it is divisible, that means that a would have to be able to go into b evenly
It cannot be factored further.
Hope that helps.
