The probability of randomly selecting a green marble from a bag is 45. If there are 110 marbles in the bag, how many are NOT green?

22
36
80
88

How do you work this out?

\text {Probability of green = } (green)/(total) = (4)/(5)

If there are total of 110 marbles,


\text {Probability of green = } = (4 * 22)/(5 * 22) = (88)/(110)

Answer : There are 88 green marbles.
