Answer 1

Answer:

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 as well which gives you 9 and 13.)
