Suppose that 3 balls are chosen from an urn which contains 5 red, 6 white and 10 blue balls. Assume X and Y represents, respectively, the number of red balls chosen and summation of chosen red and white balls.
(a) Determine the outcomes, and then represent all possible outcomes with a chart of X and Y.
(b) Determine pXY [x,y], and then from pXY [x,y] determine, pX[x] and pY [y].
(c) Determine Cov(X, Y ) and ρXY .
(d) Determine the joint CDF.

An urn contains 4 white balls and 6 red balls. A second urn contains 7 white balls and 3 red balls. An urn is selected, and the probability of selecting the first urn is 0.1. A ball is drawn from the selected urn and replaced. Then another ball is drawn and replaced from the same urn. If both balls are white, what are the following probabilities? (Round your answers to three decimal places.) - (a) the probability that the urn...

An urn contains 5 red balls and 6 blue balls. A ball is drawn. If the ball is red, it is kept out of the urn and an additional blue ball is added to the urn. Then, a second ball is drawn from the urn. If the ball is blue, then it is put back in the urn and an additional blue ball is added to the urn. Then a second ball is drawn from the urn. If the second...

Urn A contains 5 green and 4 red balls, and Urn B contains 3 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.

Suppose that there is a white urn containing two white balls and three red balls and there is a red urn containing two white balls and four red balls. An experiment consists of selecting at random a ball from the white urn and then (without replacing the first ball) selecting at random a ball from the urn having the color of the first ball. Find the probability that the second ball is red.
