A diamond can be classified as either gem-quality or industrial-grade. Suppose that 82% of diamonds are classified as industrial-grade.
(a) Two diamonds are chosen at random. What is the probability that both diamonds are industrial-grade?
(b) Six diamonds are chosen at random. What is the probability that all six diamonds are industrial-grade?
(c) What is the probability that at least one of six randomly selected diamonds is gem-quality? Would it be unusual that at least one of six randomly selected diamonds is gem-quality?
