5. Suppose that coin 1 has probability 0.7 of coming up heads, and coin 2 has probability 0.6 of coming up heads. If the coin flipped today comes up heads, then we select coin 1 to flip tomorrow. If it comes up tails, then we select coin 2 to flip tomorrow. (a) Define Xn and state space. (b) Find a transition probability matrix. (c) Suppose that the coin flipped on Monday comes up heads. What is the probability that the coin flipped on Friday of the same week also comes up heads
