    6/72

    Step-by-step explanation:

    In the first instance, the probability that it is blue would be 3/9 since there are 3 blue marbles and 9 total marbles. In the second draw, since there is one less marble, the probability will be out of 8. Since there are 2 green marbles in the second draw, the probability will be 2/8. Since we are calculating the probability of both of them together, then answer will be 2/8 * 3/9 = 6/72
