5. A device consists of k elements of type A and l elements of type B. Assume that the duration of
an element of type A follows an exponential distribution with an unknown parameter a, and the
duration of an element of type B follows an exponential distribution with an unknown parameter b.
The device breaks down when any of the elements stop working. We observe the life duration of
the whole device. Describe the statistical model of the experiment.
