The Markov Chain with states labelled 1, 2, 3 and 4 has the following one-step transition matrix
P = (1/4 1/4 1/4 1/4; 0 1 0 0; 1/4 0 1/2 1/4; 0 0 0 1)
(a) Rewrite P into the canonical form and classify the states.
(b) Calculate lim n->infinity P^n.
(c) Calculate eventual transition probabilities f11 and f22.
(d) Calculate eventual transition probabilities f32 and f34.
(e) Calculate E[N3], the average amount of time the chain spends in state 3.
