Could you please solve it step by step in a clear format so I can understand

A mouse maze consists of the paths shown in Figure 17.3. Intersection l is the maze entrance, and intersection 5 is the exit. At any intersection. the mouse has equal probabilities of selecting any 0! the available paths When the mouse reaches intersection 5, the experiment is repeated by reentering the maze at intersection 1. (a) Express the maze as a Markov chain. (b) Determine the probability that, starting at intersection l, the mouse will reach the exit after three trials. (cl Determine the long-run probability that the mouse will locate the exit intersection. ((1) Determine the average number of trials needed to reach the exit point from inter- section 1
