plz give me the solving process and necessary explanation of this question

Problem 3. Consider the following graph: the vertices are the points S aj)j e (1,2,34)) Two vertices (i, j) and (i, j') are connected if either i-n js j, 1, or j-j, and The core of the graph is C {(i,j) i,j E (2,3). The edge of the graph consists of Let Xn be the Markov process that describes a random walk on S. Define T- Explain how you can compute the probability P[XT b Xo a] where a (1,1) i=i, 1. all points that are not in the core, and b- (3,3). You should provide enough detail so that someone with a computer or calculator could use your explanation to compute P[XT 01 Optional: use Matlab/Octave/Python to do the computation. -a]. Problem 3.
