Suppose that 2% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped). (a) In a random sample of 240 shafts, find the approximate probability that between 50 and 66 (inclusive) are nonconforming and can be reworked. (b) In a random sample of 240 shafts, find the approximate probability that at least 62 are nonconforming and can be reworked,
