44. One type of jet engine has a 0.0001 probability of failure while in flight. For a jet that has four of these engines, what is the probability of at least two of them failing?
11.3.81 Q22 In a certain four-engine vintage aircraft, now quite unreliable, each engine has a 12% chance of failure on any flight, as long as it is carrying its one-fourth share of the load. But if one engine fails, then the chance of failure increases to 24% for each of the other three engines. And if a second engine fails, each of the remaining two has a 36% chance of failure. Assuming that no two engines ever fail simultaneously, and...
Assume an airplane has 4 engines each failing with probability of 0.0001. What is the probability that at least one engine fail? (Hint: Think about the complement event and its probability first) A. 0.9999^4 B. 1 - 0.9999^4 C. 0.0001^4 D. 1
10) Empire airlines flies two engine aircraft. At times the engines fail in flight and the aircraft can fly with only one functioning engine, but they need at least one. The maintenance department of Empire airlines has a goal to have at least 97% of the engines working at any time in flight. If they are not meeting this goal they have to perform additional preventative maintenance on the engines. The maintenance crew chief took a random sample of 400...

Please show all work A company manufactures impellers for use in jet turbine engines. One of the operations involves grinding a particular surface finish on a titanium alloy component. Two different grinding processes can be sued, and both processes can produce parts at identical mean surface roughness. The manufacturing engineer would like to select the process having the least variability in surface roughness. A random sample of n1= 25 parts from the first process results in a sample standard deviation...

(3) In a communication system the signal sent from point a to point b arrives by two paths in parallel. Over each path the signal passes through two repeaters (in series). Each repeater in one path has a probability of failing (becoming an open circuit) of 0.005. This probability is 0.008 for each repeater in the other path. All repeaters fail independently of each other Find the probability that the signal will not arrive at point...
