You’re a structural engineer working for a company that produces beams for use in residential home construction. You’ve found that 82% of all beams pass a rigorous inspection before being put to use. Assume that successive beams pass or fail inspection independently of one another. a. P(all of the next three beams pass) b. P(at least one of the next three beams fails) c. P(exactly one of the next three beams passes) d. P(at most one of the next three beams passes) e. Given that at least one of the next three beams passes inspection, what is the probability that all three pass?
