First you must add up all the marbles in the bag.
3 blue marbles
4 green marbles
5 red marbles
3 + 4 + 5 = 12
You are looking for the probability of picking up either a green or red marble.
So not counting blue marbles, there are 9 green and red.
9/12 = 0.75
The probability of picking up either a green or red marble is 75%.
