One ball is drawn from the bag. What is the probability that the ball is red, given that the ball is odd-numbered? (Enter your probability as a fraction.) |:| Need Help? _ _ (a) A box contains 6 red balls, 4 white balls, and 10 black balls. Two balls are drawn at random from the box (with replacement of the rst before the second is drawn). What is the probability of getting a red ball on the first draw and a white ball on the second? (Enter your probability as a fraction.) (b) Answer part (a) if the first ball is not replaced before the second is drawn. (Enter your probability as a fraction.) (c) Are the events in part (a) or in part (b) independent? Explain. Since the ball was replaced the events in part (a) are iselecti v .
