Step-by-step explanation:
Answer:
tienes que hacer cuadritos
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.)
