Explanation / Answer

E) p = 0.08

n = 15

This is a binomial distribution.

P(X = x) = 15Cx * 0.08x * (1-0.08)15-x

P(X = 7) = 15C7 * 0.087 * 0.928 = 0.0001 (ans)

The probability that 7 out of 15 customers make a purchase is 0.0001, assuming that 8% of customers make a purchase. Therefore it is not likely that randomly selecting 15 customers would result in 7 customers who made a purchase.
