Answer :
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.)

Solution: The probability that he will not get red marbles is [tex]\frac{37}{49}[/tex].
Explanation:
It is given that the john has 12 red marbles, 20 green marbles and 17 blue marbles in his bag.
The total number of marbles in the bag is [tex]12+20+17=49[/tex], therefore the number of total outcomes is 49.
If john will not get red marble it means he get blue and green marble, therefore the number of possible outcomes is [tex]20+17=37[/tex].
The probability is the ratio of possible outcomes and total outcomes.
Probability of not getting red marble =[tex]\frac{37}{49}[/tex].
Therefore, the probability that he will not get red marbles is [tex]\frac{37}{49}[/tex].
