In one of its Spring catalogs, L.L. Bean advertised footwear on 26 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. In words, dene the random variable X. 0 the number of pages in the catalog 0 the number of pages we must survey until we nd one that advertises footwear O the number of pages that advertise footwear O the number of footwear styles 0 the number of times a page could be picked List the values that X may take on. O x: 1, 2, 26 O X=o,1,2,....2o O X=1,2,...2o O x=o,1,2,...,2s O x=o,1,2,...,192 Give the distribution of X. (Enter exact numbers as integers, fractions, or decimals.) x~|7v|( , ) How many pages do you expect to advertise footwear on them? (Round your answer to the nearest whole number.) || Is it probable ttlat all twenty will advertise footwear on them? Why or why not? (Round your answer to two decimal places.) , because the probability that all twenty will advertise footwear is What is the probability that fewer than nine will advertise footwear on them?

We are interested in the number of pages that we must randomly survey until we nd one that has footwear advertised on it. Dene the random variable X.

(Round your answer to four decimal places.) Part (i) 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.)
