Step-by-step explanation:
1. To find the answer, add up all the marbles.
4+5+7= 16
2. Because 16 is the total number of outcomes, it will be the denominator.
3. Because 5 is the number of desireable outcomes, it will be the numerator.
(Note: the decimal equivalence is 0.3125).
(Note: the ratio equivalence is 5:16).
