R = red marbles = 42 B = blue marbles = 15 G = green marbles = 8 O = orange marbles = 3 T = total number of marbles = R + B + G + O = 42 + 15 + 8 + 3 = 68 First, lets calculate how many marbles are NOT orange : NO = Not Orange marbles = T - O = 68 - 3 = 65 The probability of getting a marble that is NOT orange is : NO / T = 65 / 68

95.5% because when you add them up it give 68 in total and there is only 3 orange marbles so you divide 100/68 and then multiply the asnwer of that division by 65.
