20+23+20+15= 78

78 is the total amount of marbles in the jar. It is our denominator.

20/78 = green, simplify = 10/39 is the probability you will pick green.

23/78 = orange, 23/78 is simplified so it is the probability you will pick orange.

20/78 = red, simplify = 10/39 is the probability you will pick red
