Krugen Industrial smoothing produces ball bearings. after inspection, it has generally been found that 12% of bearings must be scrapped (because they are too small), 65% are within specifications (can be used immediately), and the remaining 23% must be polished down (because they are too big). out of a random sample of 14 bearings, what is the probability that fewer than two bearings must be scrapped?
