A bag contains 6 green marbles, 2 blue marbles, and 3 white marbles. Gwen draws 1 marble from the jar and replaces it. Jeff then draws 1 marble from the jar. What is the probability that Gwen draws a blue marble and Jeff draws a white marble?

OpenStudy (kinggeorge):

Find the probability of drawing a blue marble, and then multiply it with the probability of drawing a white marble.

OpenStudy (lilai3):

2/11*6/11?

OpenStudy (kinggeorge):

white, not green, so it should be 2/11 * 3/11

OpenStudy (lilai3):

oops

OpenStudy (lilai3):

o.. so it's...6/11?

OpenStudy (kinggeorge):

\[{2\over11} \cdot {3\over11}={2\cdot3 \over 11\cdot11}={6\over121}\]

OpenStudy (lilai3):

oh.... thank you very much!

OpenStudy (kinggeorge):

OpenStudy (lilai3):
