This is where students hit a wall. Problems involving the $m(t)$ and the renewal reward theorem are notoriously subtle. For example, Problem 3.12 (the "inspection paradox") requires an intuitive explanation that software cannot generate. A robust solution includes both the mathematical derivation (using size-biased sampling) and a logical interpretation.

A Markov chain has states 1,2,3 with P(1→2)=0.5, P(1→3)=0.5; P(2→1)=0.4, P(2→3)=0.6; P(3→3)=1. Find probability of eventual absorption in state 3 starting from 1. This is where students hit a wall
