Please provide the function as well.

Urn A contains three balls labeled from 1 to 3 and urn B contains 2 balls labeled from 1 to 2. A ball is randomly selected from urn A and another ball is randomly selected from urn B. Find the joint probability mass function of X and Y when (a) X is the largest value obtained on the selected balls and Y is the sum of the values; (b) X is the value on the ball from urn A and Y is the larger of the two values; (c) X is the smallest and Y is the largest value obtained on the balls.

    Urn A contains 7 yellow balls and 3 red balls. Urn B contains 10 yellow balls and 7 red balls. Urn C contains 12 yellow balls and 4 red balls. An urn is picked randomly (assume that each urn is equally likely to be chosen), and then a ball is picked from the selected urn. What is the probability that the chosen ball came from urn B, given that it was a yellow ball?

    Urn A contains 5 green and 3 red balls, and urn B contains 2 green and 6 red balls. One ball is drawn from urn A and transferred to Urn b. Then one ball is drawn from urn B and transferred to urn A. Let X=the number of green balls in urn A after this process. List the possible values for X and then find the entire probability distribution for X.
