3. (Sampling With Replacement) An urn contains 2 black and 3 white balls. Two balls are drawn at random with replacement. The probability of selecting one ball of each color is: (a) 0.16 (b) 0.48 (c) 0.84 (d) 0.52 (e) 0.90 4. (Sampling Without Replacement) Suppose that two balls are drawn from the urn at random without replacement. The probability of selecting at least one white ball is: (a) 0.10 (b) 0.30 (c) 0.70 (d) 0.60 (e) 0.90
