It is anticipated that 1% of the time, a machine-producing vehicle pistons will generate a faulty piston. Assume this estimate is right and a random sample of 80% of the pistons generated by this machine is taken. Answer the following questions. (If required, reference a formula list.)  (a) Determine the number of faulty pistons in the sample by calculating the mean of the relevant distribution (that is, the expectation of the relevant random variable). Do not round your answer.
