#5.62 A certain airplane has 2 self-supporting alternators to put up electrical power. The opportunity that a given alternator ordaining catch on a 1 hour flight is 0.2. What is the hazard the: (a). both will go away? (b). neither will fail? (c). hotshot 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 propel in the united States will egress in a calamitousity. Over a lifetime, an average US driver takes 50,000 trips (a) what is the probability of a fatal accident all oer a lifetime? beg off your reasoning care deary. (Hint Assume independent events. Why might the self-assertion of independence be violated?

) (b). Why might a driver be tempted non to occasion a seat pat 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 outmatch 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
