Binomial Distribution (Optional) · Example 8

A store releases a 560-page art supply catalog. Eight of the pages feature signature artists. Suppose we randomly sample 100 pages. Let X = the number of pages that feature signature artists.

(a) What values does x take on?
(b) What is the probability distribution? Find the following probabilities:
(a) the probability that two pages feature signature artists
(b) the probability that at most six pages feature signature artists
(c) the probability that more than three pages feature signature artists
(c) Using the formulas, calculate the (i) mean and (ii) standard deviation.
