Question

Consider a Bernoulli process {Xn, n = 0, 1, 2,...} with Success probability p = 0.75. Define Yn = 0 if Xn = 0 and Xn-1 = 0, Yn = 1 if Xn = 0 and Xn-1 = 1, Yn = 2 if Xn = 1 and Xn-1 = 0, and Yn = 3 if Xn = 1 and Xn-1 = 1. a) Prove {Yn, n = 1, 2,...} is a Markov chain. b) Write the one-step transition matrix for it.

Step 1

..} is a Markov chain, we need to show that the probability of the next state Yn+1 depends only on the current state Yn and not on the previous states Yn-1, Yn-2, ... We can write the conditional probability as follows: P(Yn+1 = y | Yn = x, Yn-1 = w, ...) Since Show more…
