    Sum of all marbles in the bag is 8+4+5 = 17.

    Sum of red and blue marbles is 8+5 = 13.

    Now, because you are picking only 1 marble it is impossible for it to be both red and blue. You would need to pick at least 2 marbles to have a chance that one is red and one is blue.

    The answer is B. 0
