Consider the two-unit system with standby redundancy discussed in example 5.5 a) on condition that the lifetimes of the units are exponential with respective parameters λ₁
and λ₂. The other model assumptions listed in example 5.5 remain valid.

Describe the behaviour of the system by a Markov chain and draw the transition graph.
