Identify all communicating classes. For instance, for a DTMC with states {0,1,2}, if 0 and 1 communicate with each other, but neither does with 2, then the states can be classified in communicating classes as {0,1}, {2}.

Draw the state transition diagram of the DTMC on your scratch paper with state transitions and corresponding transition probabilities. Leave the Canvas answer section blank.
