Let be the sum of independent rolls of a fair
Let be the sum of independent rolls of a fair (cubicle) die.
(a) Is X [n] a Markov chain?
(b) Define a new process according to Y[n] = X[n] mod 3. That is, Y[n] Ɛ{ 0, 1, 2} is related to X [n] X [n] = 3q+ Y[n] for a non- negative integer q. Find the transition probability matrix for the process Y [n].
(c) Now suppose Z [n] = X [n] mod 5. Find the transition matrix for Z [n].
