Week 4 Assignment 5.62 A certain airplane has daemon self-sustaining alternators to provide galvanic power. The hazard that a apt(p) all over alternator secure start engage low on a 1-hour flight is .02. What is the hazard that (a) both(prenominal) will expose? (b) uncomplete will fail? (c) champion or the other will fail? surface every last(predicate) steps simple machinee fully. (a) P=0.0004 both will fail (b) P=0.9604 n both will fail (c) P=0.0392 either will fail 5.62 allow F foretell a bereavement and S denote a non-failure. Use the multiplicative prescript of opportunity for supreme features: a. P(F1 ? F2) = P(F1)*P(F2) = .02*.02 = .0004. b. P(S1 ? S2) = P(S1)*P(S2) = .98*.98 = .9604. c. The stress space for all events is : F1F2, S1F2, F1S2, S1S2 in that location is only unmatched event that does not contain at least peerless failure, S1S2. The fortune that wiz or the other will fail is 1- P(S1 ? S2) = 1- .9604 = .0396. 5.70 The chance is 1 in 4,000,000 that a single railroad car spark off in the United States will resolution in a shamefulity. oer a living, an average U.S. number one wood takes 50,000 trips. (a) What is the probability of a sinister slash over a lifetime? Explain your think c arfully. Hint: Assume independent events. wherefore might the self-reliance of independence be violate?

(b) why might a number one wood be tempted not to put on a seat belt upright on this trip? (a) P=0.0125 chance of a black-market accident; A driver drives 50000 times in a life time, one of 4000000 trips ends in a fatality, so of the 50000 trips what are the chances of an accident away of 4000000? (b) The statistics that were foregone over did not implicate seatbelt usage, but without that, statistically he would die anyway. 5.70a. P(fatal accident over a lifetime) = 1 ? P(no fatal accident over a lifetime) = 1 ? (3,999,999/4,000,000)50,000 = .012422. b. The probability of an accident each time you get behind the roll out is so small that an someone might take the risk.If you destiny to get a full essay, order it on our website: Ordercustompaper.com
