Suppose that the proportions of blood phenotypes in a particular population are as follows: A B AB CI 0.48 0.08 0.05 0.39 Assuming that the phenotypes of two randomly selected individuals are independent of one another, what is the probability that both phenotypes are 0? {Enter your answer to four decimal places.) |:| What is the probability that the phenotypes oftwo randomly selected indiyiduals match? {Enter your answer to four decimal places.) |:| A boiler has four identical relief valves. The probability that any particular valve will open on demand is 0.94. Assume independent operation of the valves. Calculate P(at least one valve opens). (Round your answer to eight decimal places.) Calculate P(at least one valve fails to open). (Round your answer to four decimal places.)
