Figure 3.9b from our textbook contains seven states. In principle, one could draw a transition between any two states, for a total of 42 different transitions (do you see why this is true?). Questions

1. List all of the possible transitions, e.g. all of the transitions that could be allowed and would be possible. Give an example of what could cause each transition.

2. List all of the impossible transitions, e.g. all of the transitions that cannot occur. Explain why you believe each transition is impossible.
