A company produces two types of CDs, CD-R and CD-RW. The product CD-R constitutes 35% of total production. About 5% of the company’s production is defective, of which 40% is CD-R. Suppose a CD is selected at random from today’s production.
a Display these facts using a Venn diagram.
b What is the probability that the selected CD is defective?
c What is the probability that the selected CD is a CD-RW?
d What is the probability that a CD-R is selected given that a defective is the selected CD?
