Consider 2 urns.
Urn 1 has 2 White Balls and 1 Black Ball. Urn 2 has 1 White Ball and 2 Black Balls. Suppose that one ball is randomly drawn from Urn 1 and put into Urn 2. Then balls are selected one at a time without replacement from Urn 2 until a White Ball is obtained. Let Y be the number of balls drawn from Urn 2 until a white ball is drawn. Find the pdf of Y and use it to find ExpectedValue(Y) and Variance(Y).

4. There are 1 white and 2 black balls in urn A, and 100 white and 100 black balls in urn B. One of the balls from urn B is randomly chosen and put in urn A. Then a ball is randomly chosen from urn A. What is the probability that it was the one from urn B if it is known that it is white?
Suppose we have two urns (a left urn and a right urn). The left urn contains N black balls and the right urn contains N red balls.
Suppose we have two urns (a left urn and a right urn). The left urn contains N black balls and the right urn contains N red balls. Every time step you take one ball (chosen randomly) from each urn, swap the balls, and place them back in the urns. Let Xm be the number of black balls in the left urn after m time steps. Find the Markov chain model and find the unique stationary distribution when N=5

Consider 3 urns. The urn A contains 5 white balls and 10 red balls, the urn B contains 9 white balls and 6 red balls and the urn C contains 4 white balls and 9 red balls. A ball is selected from ballot box 1 and placed in ballot box 2, then one ball is taken from ballot box 2 and placed in ballot box 3. Finally, a ball is taken from ballot box 3. What is the probability that...

2. An urn contains six white balls and four black balls. Two balls are randomly selected from the urn. Let X represent the number of black balls selected. (a) Identify the probability distribution of X. State the values of the parameters corresponding to this distribution (b) Compute P(X = 0), P(X= 1), and P(X= 2). (c) Consider a game of chance where you randomly select two balls from the urn. You then win $2 for every black ball selected and...
