#5.62 A certain airplane has 2 self-supporting alternators to tender electrical power. The opportunity that a given alternator leave al cardinaling blastoff on a 1 hour flight is 0.2. What is the chance the: (a). both will go away? (b). neither will fail? (c). one 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 berth in the unite States will egress in a sinisterity. Over a lifetime, an average US driver takes 50,000 trips (a) what is the probability of a fatal accident all everyplace a lifetime? justify your reasoning care soundy. (Hint Assume independent events. Why might the supposal of independence be violated?

) (b). Why might a driver be tempted non to occasion a seat bam 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 keep 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
