    P (black) = 2/3

    Step-by-step explanation:

    We need to find the total number of marbles

    2 red marbles + 3 white marbles + 10 black marbles = 15 marbles

    To find the probability that Sam chose a black marble, we take the number of black marbles and divide by the total number of marbles

    P (black) = black marbles/total marbles

    = 10/15

    Divide the top and bottom by 5

    = 2/3
