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.
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).
