Shannon Acevedo Individual Exercises Week Four Questions: 5.62 A certain aeroplane has 2 free alternators to provide electrical power. The hazard that a precondition alternator go away rat on a 1-hour flight is .02. What is the probability that (a) two forget flush it? (b) uncomplete forget fail? (c) One or the other will fail? assign all steps c befully. Answer: N = 2, p = .02, a = alternator 1, b = alternator 2 A) Both will fail (.02)(.02) = 0.0004, opportunity that both will fail is 0.0004 or 0.04% B) 1-( Pa + Pb) + (P(both fail)) = (1 - 0.04) + 0.0004 = 0.9604 Neither will fail is 0.9604 or 96.04% C) Pa + Pb (P(both fail)) = 0.02 + 0.02 0.0004 = 0.0396 One or the other will fail is 0.0396 or 3.96% _____________________________________________________________________________ Questions: 5.70 The probability is 1 in 4,000,000 that a sensation auto elusion in the United States will forget in a sinisterity. oer a animation, an average U.S. number one wood takes 50,000 jaunts. (a) What is the probability of a fatal throw anyplace a lifetime? Explain your think carefully. Hint: Assume independent events. Why might the self-assertion of independence be break? (b) Why might a driver be tempted non to use a spot belt just on this trip? N = 2, p = 0.00000025 (1/4,000,000), a = fatal stroke, b = no fatal accident P (a fatal accident over a lifetime) = 1 - P (NO fatal accident over a lifetime) Pa = 1 Pb Pa = 1 0.00000025 Pa = 0.99999975 ^ 50000 = 0.987577799 Pa = 1 0.987577799 Pa = 0.012422201 Probability of a fatal accident over a drivers lifetime is 0.012422201 (1.24%). The assumption of independence is violated because drivers do not go the homogeneous route or the same distance for every single trip. They could take a firm trip to the store, or go on a trip across the country. The drivers themselves are not the same for each trip either. The driver could be not feeling well, could be intoxicated, or thei! r driving habits might...If you hope to get a full essay, install it on our website: OrderCustomPaper.com
