Exercises from E-Text RES/341 May 2nd 20 Question #1 (5.62) A certain airplane has two single-handed alternators to tender galvanising power. The hazard that a given alternator get out contain on a 1-hour flight is .02. What is the probability that (a) twain will fail? (b) Neither will fail? (c) integrity or the other will fail? Show all travel carefully. act: If the probability of failure is .02 than the probability of non failing is .98 (a) both will fail= 0.02 * 0.02 = 0.0004 (b) Neither will fail= 0.98 * 0.98 = 0.9604 (c) nonpareil or the other will fail = 0.98 * 0.02= (0.0196) + 0.98* 0.02= (0.0196) = 0.0392 Question #2 (5.70) The probability is 1 in 4,000,000 that a single car slick in the United States will result in a sinisterity. Over a life story, an average U.S. device driver takes 50,000 trips. (a) What is the probability of a fatal possibility everyplace a lifetime? Explain your reasoning carefully. Hint: Assume independent ev ents. wherefore might the assumption of independence be go against? (b) why might a driver be tempted not to engagement a seat charge just on this trip? Answer: (a) What is the probability of a fatal virgule over a lifetime? 1/4,000,000 = 0.00000025 is the probability of a fatality, so therefore 0.99999975 relates to not having a fatality. N = 2, p = 0.

00000025, a = fatal happening, b = no fatal accident Pa = 1 Pb Pa = 1 0.00000025 Pa = 0.99999975 ^ 50000 = 0.987577799 Pa = 1 0.987577799 Pa = 0.012422201 or the probability of a fatal accident over a lifetime is 0.012422201 or 1.24%. One mountain assume independence; when we are ! presumptuous that none of our front impetuous experiences had all fatal accidents does not make it any less likely that we will brace an accident. Average drivers issue this is not true, that the probability of a fatal accident decreases as we get more than experience driving and become more mature. (b) Why might a driver be tempted not to use a seat belt just on this trip? Well, one should not be so tempted, or...If you motivation to get a full essay, rear it on our website: BestEssayCheap.com
