Question 4
A recording company obtains the blank CDs used to produce its labels from three
compact disk manufacturers:
I, II, and III.
The quality control department of the
company has determined that 3% of the compact disks produced by manufacturer I are
defective, 4% of those produced by manufacturer II are defective, and 4% of those
produced by manufacturer III are defective.
Manufacturers I, II, and III supply 31%,
34%, and 35%, respectively, of the compact disks used by the company.
What is the
probability that a randomly selected label produced by the company will contain a
defective compact disk?
