A bag contains 6 red marbles, 5 blue marbles and 8 green marbles. If three marblesare drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be green?

$$6 \over 19$$ chance for the first marble

$$5 \over 19$$ chance for the second marble

$$8 \over 19$$ chance for the third marble.

Because they all "rely" on each other, the probability is the product of all 3 cases.

Good try Builderboi, but not quite right.

8/19 * 7/18 * 6/17 =

OR

8C3 /  19C3  =

this is two different ways to do it, the answer is the same each time.
