Suppose a Markov chain has three states, A, B, and C. It changes to a different state each step (no loops). The probability it will change from A to B is 0.8, the probability it will change from B to A is 0.2, and the probability it will change from C to A is 0.2. Find the long-term distribution for this Markov chain. What proportion of the time will it spend at state A
