    Since she puts the marbles back, these events are dependent on each other

    so

    probability = (desired outcomes) / (total possilbe)

    8+5=13=total

    probailigy of blue=8/13

    gree=5/13

    so if she draws theem in that order then

    8/13 times (since there is one less, - 1 of 13) 5/12 times (assume 1 grreen was drawn from previus drawing) 4/11 times (assume as previus) 3/10

    so

    8/13 times 5/12 times 4/11 times 3/10=4/143=C

    the answer is C 4/143
