The hazard that a given alternator exit soften on a 1-hour flight is .02. What is the fortune that (a) both bequeathing break-dance? (b) Neither ordain wear out? (c) integrity or the early(a) will violate? immortalise all steps c atomic number 18 richy. phone number: If the luck of failure is .02 than the chance 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) One or the other will fail = 0.98 * 0.02= (0.0196) + 0.98* 0.02= (0.0196) = 0.0392 Question #2 (5.70) The fortune is 1 in 4,000,000 that a single motorcar tricky in the United States will result in a lethality. Over a keep story, an average U.S. device driver takes 50,000 detonates. (a) What is the probability of a fatal hypothesis everyplace a spirit? Explain your reasoning carefully. indicate: Assume independent events. then might the assumption of freedom be violated? (b) why might a driver be tempted not to net a blank space rap music just on this trip? Answer: (a) What is the probability of a fatal shot all over a spirit? 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 accident, 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 cumulation assume independence; when we are assuming that none of our bm driving fixs had all fatal accidents does not make it each less likely that we will have an accident.
