1. An alternate approach to finding the stationary distribution of a Markov chain (rather than finding P^n), is to use the fact that if [X1 X2 X3] = the vector X transpose is a stationary distribution for a Markov chain with three states, then the vector X transpose P= the vector X transposewhere P is the 3x3 probability transition matrix for the Markov chain. This gives three equations in X1, X2, X3, and we have the fourth condition that X1+X2+X3=1. A system of 4 equations is 3 unknowns which, if has a solution, will provide the probabilities of the stationary distribution.Use this approach to find the stationary distribution for the Markov chain with probability transition matrix 01/6 1/2 1/32/3 1/3
