Bulbs fails independently

Traffic engineers install 9 street lights with new bulbs. The probability that a bulb will fail within 50040 hours of operation is 0.23. Assume that each of the bulbs fails independently.

a) What is the probability that fewer than two of the original bulbs will fail within 50040 hours of operation?

(b) What is the probability that no bulbs will have to be replaced within 50040 hours of operation?
