box contains 7 red balls, 5 white balls, and 4 blue balls. A ball is selected at random from the box, its color is noted, and then the ball is replaced. (a) Find the probability that out of 8 balls selected in this manner, 4 are red, 3 are white, and 1 is blue. (b) If the 8 balls were picked at the same time, find the probability that 4 are red, 3 are white, and 1 is blue
