A bag contains 2 orange marbles, 14 green marbles, and 17 blue marbles. If two marbles are chosen randomly from the bag and not replaced, what is the probability that the first marble is green and the second marble is blue?

OpenStudy (anonymous):

There are 33 total marbles. The probability of: (first G, then B) is: P(first G) x P(then B, given that first is G) (# green marbles)/(total # of marbles) x (# of blue marbles)/(1 less than total # of marbles)

OpenStudy (anonymous):

So to start, with that first fraction, how many green marbles and how many total marbles are there?

OpenStudy (anonymous):

so 14/33 x 17/32?

OpenStudy (anonymous):

Yes! You got it!
