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.)

Answer:
Number = 15.
Step-by-step explanation:
Given : If you multiply a number by 3 and then subtract 5, you will get 40.
To find : what is the number.
Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.
According to question :
Let the number = x
Multiply is with 3 = 3x
Subtract 5 from it we get 40 .
3x -5 = 40
On adding both sides by 5
3x = 45 .
On dividing both sides by 3
x = 15.
Therefore, Number = 15.
