Consider a Markov chain
\begin{tabular}{c|cccc}
&
By drawing an appropriate diagram, determine the communicating classes of the chain, and classify them as either open or closed. Compute the following transition and hitting probabilities:
-
$\mathbb{P}\left(X_{n}=b \mid X_{0}=d\right)$ for a fixed$n \geqslant 0$ -
$\mathbb{P}\left(X_{n}=c\right.$ for some$\left.n \geqslant 1 \mid X_{0}=a\right)$ .
