Consider the DTMC below: -5 So === cifen ciles 121 9 1 $4 1+1=1414 1|1 12 $5 0/0 Let A = {s3} and B = {s2}. 1. Compute the probability measure of the union of the following cylinder sets: Cyl(sos1), Cyl(S05556), Cyl(S05585453), Cyl(505186) 2. Compute the probability, from each state of the Markov chain, of reaching a state in A within 4 steps. 3. Compute the probability, from each state of the Markov chain, of reaching a state in A. 4. What is the probability, from the initial state, of reaching the set of states AUB? 5. What is the probability, from the initial state, that a state from AUB is visited infinitely often?
