A rat runs through the maze shown in Figure. At each step it leaves the room it is in by choosing at random one of the doors out of the room.

  • Give the transition matrix [math]\mat{P}[/math] for this Markov chain.
  • Show that it is an ergodic chain but not a regular chain.
  • Find the fixed vector.
  • Find the expected number of steps before reaching Room 5 for the first time, starting in Room 1.
