A diamond can be classified as either gem dash quality or industrial dash grade. Suppose that 93% of diamonds are classified as industrial dash grade. (a) Two diamonds are chosen at random. What is the probability that both diamonds are industrial dash grade? (b) Six diamonds are chosen at random. What is the probability that all six diamonds are industrial dash grade? (c) What is the probability that at least one of six randomly selected diamonds is gem dash quality? Would it be unusual that at least one of six randomly selected diamonds is gem dash quality?
