#5.62 A certain airplane has 2 self-supporting alternators to proposition electrical power. The opportunity that a given alternator willing guess on a 1 hour flight is 0.2. What is the chance the: (a). both will go away? (b). neither will fail? (c). i 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 unite States will egress in a ingloriousity. Over a lifetime, an average US driver takes 50,000 trips (a) what is the probability of a fatal accident all all over a lifetime? inform your reasoning care affluenty. (Hint Assume independent events. Why might the boldness of independence be violated?

) (b). Why might a driver be tempted non to occasion a seat belt out 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: OrderEssay.net
