John has a bag of marbles that contains 12 red marbles, 20 green marbles, and 17 blue marbles.

What is the probability that he will **not** get a red marble?

12 red marbles 20 green marbles 17 blue marbles Total amount: 39 marbles
39 (total) - 12 (red) = 27.
John has a probability of 27/39 that he will not pick a red marble out of the bag. If you want to simplify your fraction by dividing both numbers by 3 to make it even more accurate, an even better answer would be 9/13.
(so all you do is divide 27/3 and divide 39/3 aswell which gives you 9 and 13.)

John has a probability of 49 37 ​ of not drawing a red marble from his bag containing 12 red, 20 green, and 17 blue marbles. This result was obtained by calculating the number of non-red marbles and dividing by the total number of marbles. Thus, there is a high chance he will pick a marble that is not red.
