a) LetK5 be the graph with vertices {1,2,3,4,5} and edges {12,13,14,15,23,24,25,34,35,45} (so every pair of vertices are joined). Consider the random walk on K5.

i) How do you know that this has a unique equilibrium distribution?

ii) How do you know that it has a limiting distribution?

iii) Without solving any equations write down the equilibrium distribution.

thanks for any help.
