An urn contains 4 red balls and 3 green balls. Two balls are drawn randomly. (a) Let Z denote the number of green balls in the sample when the draws are done without replacement. Give the possible values and the probability mass function of Z. (b) Let W denote the number of green balls in the sample when the draws are done with replacement. Give the possible values and the probability mass function of W.
