A bowl contains only red marbles, blue marbles and green marbles. The probability of selecting a red marble from the bowl is 3/13. The probability of selecting a blue marble from the bowl is 2/5. There are fewer than 100 marbles in the bowl. What is the probability of selecting, at random and without replacement, a green marble and then a red marble from the bowl on the first two selections?

Express your answer as a common fraction.

3/13 = .23 for red marble

2/5 = .40 for blue marble

?? for green marble.

How many fewer than 100?

Probability of both/all events occurring is found by multiplying the probabilities of the individual events.

Say there are 65 marbles in the bag. Then there will be 15 red marbles, 26 blue marbles, and 24 green marbles. so without replacement the probability of receiving a green marble and then a red marble would be (24/65)(15/64) which is 9/104
