The settling of unwanted material in a mold is causing some defects in the output. Based on recent data, it is estimated that 5% of the output has one or more defects. In spot checking some parts, an inspector randomly selects two parts. Find the probabilities that:
(a) the first part is defect free.
(b) the second part is defect free.
(c) both parts are defect free.
(d) one of the parts is acceptable.
(e) at least one part is acceptable.
