|. Reconsider the continuous-time Markov chain example discussed in class. Assume nowt hat the machines are not serially connected, and if one of them fails, the other continues to function,

and therefore may also fail while the first machine is being repaired. (a) Develop the diagram for this Markov chain. (b) Write down the time-dependent ordinary differential equations for this Markov chain. (c) Construct the steady-state equations.
