4. A bag contains 20 white, 15 blue, 10 red, 8 yellow, and 7 green balls. (a) Suppose a ball is randomly selected. What is the probability that it is yellow? (b) Suppose a ball is randomly selected. What is the probability that it is a yellow or green (c) A ball is selected from the bag, its color noted, then replaced. You then draw a second bail, note its color and then replace the ball. What is the probability that the first one is white and the second one is green? (d) Three balls are selected at random without replacement.
