A manufacturing company performs a quality-control analysis on the ceramic tile it produces. Suppose a batch of 20 tiles has 6 defective tiles. If 5 tiles are sampled at random, what is the probability that exactly 1 of the sampled tiles is defective? How many ways can 5 tiles be selected from 20 tiles? 15504 ways (Type a whole number.) The probability that exactly 1 of the sampled tiles is defective is (Round to four decimal places as needed.)
