1. Suppose a quality manager for XYZ Computers has collected the following data on the quality status of disk drives by suppliers. She inspected a total of 700 disk drives and derived the following results Drive Status Working Defective Supplier Company A Company B Company C Company D 120 10 180 15 50 5 300 20 (a) Based on these inspection data, what is the probability P (B) of ran- domly selecting a disk drive from Company B? (b) What is the probability P (Defect B) of a defect given that Company B supplied the disk drive? (c) Suppose a defect has been found. Can we use either P (B) or P (Defect B) derived in parts a and b as the percentage to split the cost of defective driver to supplier B? If not, what is the correct percentage? State vour reason clearly,

(a) Based on these inspection data, what is the probability P (B) of ran- domly selecting
a disk drive from Company B?
(b) What is the probability P (Defect B) of a defect given that Company B supplied the
disk drive?
(c) Suppose a defect has been found. Can we use either P (B) or P (Defect B) derived in
parts a and b as the percentage to split the cost of defective driver to supplier B? If not,
what is the correct percentage? State your reason clearly.
