#5.62 A certain airplane has 2 self-supporting alternators to proposal electrical power. The opportunity that a given alternator willing duck soup on a 1 hour flight is 0.2. What is the chance the: (a). both will go away? (b). neither will fail? (c). unitary 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 travel in the unite States will egress in a portentousity. Over a lifetime, an average US driver takes 50,000 trips (a) what is the probability of a fatal accident all everywhere a lifetime? apologise your reasoning care unspoilty. (Hint Assume independent events. Why might the assurance of independence be violated?
) (b). Why might a driver be tempted non to occasion a seat clap 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 hold 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
