Answer 1

12 over 20 is not on this list

Answer 2

12 over 20

To calculate the probability of drawing a red or blue marble, you need to add the number of red marbles (5) and blue marbles (7) together, then divide that sum by the total number of marbles in the bowl (20).

5 red marbles + 7 blue marbles = 12
12 out of 20 total marbles = 12/20 or 12 over 20

Answer 3

In that case, the correct response would be:

7 over 20

This is the probability of drawing a red or blue marble, out of the total of 20 marbles in the bowl.
