2. Let X be the random occurrence number of failed components among 5 independent and identical components. Each component has a failure probability of 0.01 during an operating period. Find the probability of exact one failure. [3] 3. An electric power system supplied from a total of 125 generating units. Calculate the probability of having (a), (b) 7, and (c) 11 units being out of service simultaneous, given that the outage rate (q) of each unit is 0.06. [3]
