    66.67% probability of selecting a black marble from the bag.

    Step-by-step explanation:

    Initially there are 16 marbles, 10 of which are black and 6 of which are red.

    A red marble is drawn and not put back. So now there are 15 marbles, of which 10 are black.

    So there is a 10/15 = 2/3 = 0.666% 7 = 66.67% probability of selecting a black marble from the bag.
