5. Consider the Markov chain (X) possessing the following transition matrix. .6 .4 0 .2 .5 .3 0 .1 .9 P = Define new random variables Y = X - X1. Then (Y) is a stochastic process, but is it a Markov chain? Answer the following questions. a. What is the state space for {Y}? b. Does {Y} satisfy the Markov property? If yes, then give the transition matrix. If not, demonstrate how the Markov property is violated.
