Question 1 Hydraulic assemblies for landing gear coming from an aircraft repair facility are inspected for defects. History shows that 8% have defects in the shaft alone, 6% have defects in the bushing alone, and 2% have defects in both the shafts and the bushings. If a randomly selected assembly is to be used on an aircraft, find the probability that it has a) A bushing defect. b) A shaft or busing defect. c) Only one of the two types of defects. d) No defects in the shafts or bushings.
