Draw the transition diagram representing a Markov chain with the transition matrix where the state S={1,2,3}. 0.0 0.2 0.8\ P=1.0 0.0 0.0 0.7 0.2 0.1/ a) Identify the communicating classes and classify them a periodic or aperiodic. b) Determine whether it is recurrent state or otherwise for each state. c) Approximate the mean recurrence times for state 1,14,, upto n = 4.
