2) Hydraulic landing assemblies coming from an aircraft rework facility are each inspected for defects. Historical records indicate that 8% have defects in shafts only, 6% have defects in bushings only, and 2% have defects in both shafts and bushings. one ot the hydraulic assemblies is selected randomly. What is the probability that the assembly has: (02 Marks) a) Bushing defect? b) Shaft or bushing defect? c) Exactly one of the two types of defects? d) Neither type of defect?

-13 points er keyboard failures can be attributed to electrical defects or ects. A repair facility currently has 25 failed keyboards, 10 of which have electrical defects and 15 of which have mechanical defects. (a) How many ways are there to randomly select 6 of these keyboards for a thorough inspection (without regard to order)? ways (b) In how many ways can a sample of 6 keyboards be selected so that exactly two have an electrical defect? ways (c) If...

13) Items under inspection are subjected to two types of defects about 70% of the items in a large lot are judged to be defect-free, whereas 20% have a type A defect alone and 10% have a type B defect alone (none have both types of defects). a) If six of items are randomly selected, find the probability that three have no defects, one has type A defect, and two have type B defect. b) What is the mean and...

(b) At a factory where bolts are produced, machines A, B, C produce respectively 25%, 35% and 40% of all bolts. Of the output of these machines, defects constitute 5%, 4% and 2% respectively. A bolt selected at random from the production turned out to be defective. What machine was the most likely to have produced this defective bolt? (give the probability it was this machine.) [5]
