Since there are 15 marbles in the first bag, 5 being blue, the probability of drawing a marble from the first bag is 1/3.
The probability of you drawing a blue marble from the second bag is 2/9, so (mainly from process of elimination) I believe that the probability is D. 2/27.
1/3 x 2/9 is a way to figure it out.  1 x 2 = 2. 9 x 3 = 27.    2/27
