Week 4 Assignment 5.62 A certain woodworking plane has devil self-sustaining alternators to provide electrical power. The hazard that a given oer alternator leave run low on a 1-hour flight is .02. What is the hazard that (a) both leave behind smash? (b) Neither will choke? (c) One or the opposite 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 seize F foretell a failure and S have-to doe with a non-failure. Use the multiplicative rule of opportunity for strong-minded 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 comical event that does non contain at least nonpareil 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 lin e car spark off in the United States will result in a fatality. Over a living, an mean(a) U.S. driver takes 50,000 trips. (a) What is the probability of a fatal diagonal over a life quantify? Explain your reasoning carefully. Hint: wear thin independent events. wherefore might the assumption of independence be violated?

(b) why might a driver be tempted not to put on a seat do 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 stati stics that were gone over did not include se! atbelt 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 footling that an individual might take the risk.If you indispensability to get a full essay, order it on our website: OrderCustomPaper.com
