In one of its Spring catalogs, L.L. Bean® advertised footwear
on 27 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.
Give the distribution of X. (Enter exact numbers
as integers, fractions, or decimals.)
x~ ? ( ? , ? )
How many pages do you expect to advertise footwear on them?
(Round your answer to the nearest whole number.)
What is the probability that you only need to survey at
most two pages in order to find one that advertises
footwear on it? (Round your answer to four decimal places.)
