23.Suppose you choose a marble from a bag containing 6 red marbles, 3 white marbles, and 4 blue marbles. You return the first marble to the bag and then choose again. Find P(red and blue).

a. 10/13
b. 9/13
c. 24/169
d. 24/13

    P(R)=6/13
    P(B)=4/13
    Since the marble is returned to the bag, the first and the second picks are independent events, and probability of both happening is the product of the two probabilities.
