Suppose you have two urns with a total of 5 balls. At each step, one of the five balls is chosen atrandom and switched from its urn to the other urn. Let X, be the number of balls in the first urnafter 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 2balls at the 12th turn?

a) A Markov chain is a stochastic process where the future state depends only on the current state…

A study of armed robbers yielded the approximate transition probability matrix shown below. The matrix gives the probability that a robber currents free, on probation, or in jail would, over a period of a year, make a transition to one of the states. То From Free Probation Jail Free 0.7 0.2 0.1 Probation 0.3 0.5 0.2 Jail 0.0 0.1 0.9 Assuming that transitions are recorded at the end of each one-year period: i) For a robber who is now free, what is the expected number of years before going to jail? ii) What proportion of time can a robber expect to spend in jail? [Note: You may consider maximum four transitions as equivalent to that of steady state if you like.]
A car rental company has two locations. Each week, 80% of the cars rented at location A are returned to location A and the rest location B. Of the cars rented at location B, 30% are returned to location B by the end of the week and the rest to location A. a. Make a transition diagram for this process. b. Write the transition matrix T for this process. cIf 50% of the company's cars start this week at location A, and 50% at location B, find the proportion of cars that will be at each location one week later Label your answers. d.

Suppose you have 52 cards with the letters A, B, C, ..., Z and a, b, c, ..., z written on them. Consider the following Markov chain on the set S of all permutations of the 52 cards. Start with any fixed arrangement of the cards and at each step, choose a letter at random and interchange the cards with the corresponding capital and small letters. For example if the letter "M/m" is chosen, then the cards "M" and "m" are interchanged. This process is repeated again and again. (a) Markov chain. Count, with justification, the number of communicating classes of this (b) Give a stationary distribution for the chain. (c) Is the stationary distribution unique? Justify your answer.

In at tropical forest, the populations of falcons and mice are related toeach other. The mice eat everything they can while the falcons eat the mice. The population sizes of falcons and mice evolve according to the rule. * At the beginning of 2023, there were 10 falcons and 40 mice. a) Approximately how many falcons and mice will there be at the beginning of 2068? b) c) Find a diagonalization, A = BDB-1, of the transition matrix A from part (b), where D is a 2x2 diagonal matrix, and B is an invertible2x2 matrix. d) Use your answer to (c) to estimate the (approximate) numbersof falcons and mice there will be at the beginning of 2058. e) what restrictions on the initial population sizes ensures the long time survival of both species in the forest
