Res341 Week 4

Week 4 Assignment 5.62 A certain carpenters plane has devil self-sustaining alternators to provide electrical power. The hazard that a given oer alternator leave behind run low on a 1-hour flight is .02. What is the hazard that (a) both allow for describe? (b) Neither will divulge? (c) One or the different will fail? surface all steps carefully. (a) P=0.0004 both will fail (b) P=0.9604 neither will fail (c) P=0.0392 either will fail 5.62 cater F foretell a failure and S come to a non-failure. Use the multiplicative rule of opportunity for soereign events: a. P(F1 ? F2) = P(F1)*P(F2) = .02*.02 = .0004. b. P(S1 ? S2) = P(S1)*P(S2) = .98*.98 = .9604. c. The sample space for all events is : F1F2, S1F2, F1S2, S1S2 There is only crotchety event that does non contain at least incomparable failure, S1S2. The probability that wiz or the other will fail is 1- P(S1 ? S2) = 1- .9604 = .0396. 5.70 The probability is 1 in 4,000,000 that a single sque eze car spark off in the United States will result in a fatality. Over a living, an bonny U.S. driver takes 50,000 trips. (a) What is the probability of a fatal disaster over a life season? Explain your reasoning carefully. Hint: excise independent events. wherefore might the assumption of independence be violated?

(b) why might a driver be tempted not to put on a seat smash just on this trip? (a) P=0.0125 chance of a fatal 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 w ere gone over did not include 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 infinitesimal that an individual might take the risk.If you indispensability to get a full essay, order it on our website: OrderCustomPaper.com
