In one of its Spring catalogs, L.L. Bean advertised footwear on 28 of its 192 catalog pages. Suppose we randomly survey 20 pages. We are interested in the number of pages that advertise footwear. Each page may be picked more than once.

What is the probability that fewer than ten will advertise footwear on them? (Round your answer to four decimal places.)

What is the probability that you only need to survey at most three pages in order to find one that advertises footwear on it? (Round your answer to four decimal places.)

How many pages do you expect to need to survey in order to find one that advertises footwear? (Round your answer to the nearest whole number.)
