A boiler has four identical relief valves. The probability that any particular valve will open on demand is 0.91. Assume independent operation of the valves. (a) Calculate P(at least one valve opens). (Round your answer to eight decimal places.) (b) Calculate P(at least one valve fails to open). (Round your answer to four decimal places.)
