Separate a bulb fault from simultaneous bulb-and-switch faults

When a large number of flashlights leaving a factory is inspected, it is found that the bulb is faulty in 1% of the flashlights and the switch is faulty in 1.5% of them. Assuming that the faults occur independently and at random, find the probability that a sample of

(i) 10 flashlights contains no faulty bulb,2 marks

(ii) 80 flashlights contains at least one flashlight with both a faulty bulb and a faulty switch.3 marks
