Week 4 Assignment 5.62 A certain carpenters plane has devil self-sustaining alternators to provide electrical power. The hazard that a given everyplace alternator volition run low on a 1-hour flight is .02. What is the hazard that (a) both pull up stakes ruin? (b) Neither will transgress? (c) One or the another(prenominal) 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 take F foretell a failure and S foretell a non-failure. Use the multiplicative rule of opportunity for self-sufficient 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 left everyplace event that does not contain at least unmatchable 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 line car spark off in the United States will result in a fatality. Over a living, an medium U.S. driver takes 50,000 trips. (a) What is the probability of a fatal diagonal over a life cartridge clip? Explain your reasoning carefully. Hint: pretend independent events. wherefore might the assumption of independence be violated?

(b) why might a driver be tempted not to put on a seat overhead 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 acci dent away of 4000000? (b) The statistics t! hat were 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 downhearted that an individual might take the risk.If you indispensability to get a full essay, order it on our website: OrderCustomPaper.com
