5.13. Consider the following Markov matrix representing a Markov chain with state
space {a,b,c,d,e}.
$$
\mathbf{P} = \begin{bmatrix}
0.3 & 0.0 & 0.0 & 0.7 & 0.0 \\
0.0 & 1.0 & 0.0 & 0.0 & 0.0 \\
1.0 & 0.0 & 0.0 & 0.0 & 0.0 \\
0.0 & 0.0 & 0.5 & 0.5 & 0.0 \\
0.0 & 0.2 & 0.4 & 0.0 & 0.4
\end{bmatrix}.
$$
(a) Draw the state diagram.
(b) List the transient states.
(c) List the irreducible set(s).
