#5.62 A certain airplane has 2 self-supporting alternators to put up electrical power. The opportunity that a given alternator go forthing dig on a 1 hour flight is 0.2. What is the prospect the: (a). both will go away? (b). neither will fail? (c). wiz of the other will fail? (a). P(A)=one alternator, P(B)= due south alternator P=P(A and B) P=1(0.2 x 0.2) P=1(0.04) P= 0.04 (b). P=(P-A) x (P-B) P=(1-0.2) x (1-0.2) P=(0.8 x 0.8) P=0.64 (c). A(P-A) + B(P-B) 0.2(1-0.2) + 0.2(1-0.2) 0.2(0.8) + 0.2(0.8) 0.16 + 0.16 P= 0.32 #5.70 The probability is 1 in 400,000,000 that a maven auto go in the unify States will egress in a pitch-blackity. Over a lifetime, an average US driver takes 50,000 trips (a) what is the probability of a fatal accident all everywhere a lifetime? explicate your reasoning care waxy. (Hint Assume independent events. Why might the trust of independence be violated?) (b). Why might a driver be tempted non to occa sion a seat belt ammunition just on this trip? (a). P (fatal accident over a lifetime) = 1 P(No fatal accident over a lifetime) P=1-4,000,000 = 3,999,999 P = 1 (3,999,999/4,000,000) ^50,000 P = 1 0.9876 P = 0.0124 (b). Drivers might not use seat belts on this trip because they may not be traveling far infinite and believe that they will arrive safely to their destination or because they forget to use their seatbelts.If you want to get a full essay, order it on our website: OrderCustomPaper.com
