SwissAir maintains a mailing list of people who have taken trips to Europe in the last three years. The airline knows that 8% of the people on the mailing list will make arrangements to fly SwissAir during the period following their being mailed a brochure. In an experimental mailing, 20 people are mailed a brochure. What is the probability that at least one of them will book a flight with SwissAir during the coming season?
This is a problem on Binomial probability.
n = 20, p = probability of "success" = 8% = 0.08, q = 1 - p = 1 - 0.08 ...
