An airline has classified its customers as high-volume travelers (assumed to be business travelers) and low-volume travelers (assumed to be leisure travelers). Eighty five percent are high volume travelers. If five people are randomly selected from a list of customers, What is the probability none are high-volume travelers?© BrainMass Inc. brainmass.com December 24, 2021, 11:45 pm ad1c9bdddf

Let X be number of high volume travelers, from given information, X has a binomial distribution with n=5 and p=0.85
Using the formula of binomial distribution,
P(none are high-volume travelers) = P(X=0) = C(5,0) * (0.85)^0 * (0.15)^5 = 0.0000759375© BrainMass Inc. brainmass.com December 24, 2021, 11:45 pm ad1c9bdddf>
