A system has two components. If either component fails, the
system fails. Failures of the components occur as two independent
Poisson processes with respective rates 1.5 and 2.2 failures per
year
Find the expected number of system failures during the next
three months
During the last two months, there have been no failures of
either component. Find the probability that the system will
experience at least two failures during the next three months
