An urn has six balls, 3 are red, 2 are blue, and 1 is green. You choose 2 at random, without replacement. Let X be the number of red balls drawn, and Y be the number of green balls drawn.

(A) Find the joint distribution of X and Y.

(B) Find the marginal distribution of X and Y.

(C) Find the conditional distribution of Y, given that X=1.

(D) E[X], E[Y], E[X2], E[Y2], E[XY], AND Cov(X,Y).

An urn contains five blue, six green and seven red balls. You choose five balls at random from the urn, without replacement (so you do not put a ball back in the urn after you pick it), what is the probability that you chose at least one ball of each color?(Hint: Consider the events: B, G, and R, denoting respectively that there are no blue, no green and no red balls chosen.)

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.
