A bag contains 4 green marbles, 6 red marbles, and 2 white marbles. Three marbles are drawn at random with replacement. With replacement means that after a marble is drawn, it is replaced before the next one is drawn. Find the probability of all three blue.

Due to the replacement, the three drawings are independent.
However the answer is zero because there are no blue marbles in the bag.
