Suppose that when a new machine is functioning well, 92% of the items produced are non-defective. Assume that a random sample of five parts produced on the machine is selected and we are interested in the number of defective parts found.
Required:
c) What is the probability that none of the parts selected will be defective?
d) What is the probability that more than five parts will be defective?
e) What is the probability that at least three parts will be non-defective?
