Consider a bag of marbles, 19 of which are green, 25 of which are blue, and 6 of which are red. Moreover, suppose 9 of the green marbles are opaque, 5 of the blue marbles are opaque, and 3 of the red marbles are opaque, and the rest of the marbles are transparent. Suppose you draw one marble from the bag and let G, B, and R be the events that the marble is green, blue, and red, respectively, and let O be the event that it is opaque. (a) Find P(RO). (b) Find P(RO). (c) Find P(R). (d) Check whether R and O are independent. Find P(BO). (f) Find P(OG). (g) Find P(BUGIO).
