An urn contains two red and two green balls. The balls are chosen at random, one by one, from the urn. If a red ball is chosen, it is removed. Any green ball that is chosen is returned to the urn. The selection process continues until all of the red balls have been removed from the urn. a) Find a transition probability matrix P. Find all states which are accessible from state 1. b) Find P(X3 = 0|X1 = 2, X2 = 1). c) Is this chain irreducible? Explain. Please answer parts a, b, and c.

Suppose you have two urns with a total of 5 balls. At each step, one of the five balls is chosen at random and switched from its urn to the other urn. Let X, be the number of balls in the first urn after n switches. a) Is {X, : n = 1,2,...} a Markov Chain? Explain. b) Define the state space and provide the one step transition matrix. c) Draw the corresponding transition graph. d) Classify the states. Are there any periodic states? e) What is the probability that, given I have 3 balls in the first urn at the 10th turn, I will have 2 balls at the 12th turn?

students in probability class can choose to take (only one exam) exam 1, exam 2, or exam 3.we know that 20% of the students choose exam 1, 50% choose exam 2, and 30% choose exam 3.moreover, we know that the probability a student who chose to take exam 1 will get the wrong address is 0.44the probability a student who chose exam 2 will get the wrong address is 0.6and a student who chose exam 3 will get the wrong address in probability 1.a student took one of the exams and got the right address. what is the probability the student chose exam 2?
