Question 919675
Keith’s Florists has 15 delivery trucks, used mainly to deliver flowers and flower arrangements in the Greenville, South Carolina, area. Of these 15 trucks, 7 have brake problems. A sample of 5 trucks is randomly selected. What is the probability that 2 of those tested have defective brakes?
------------
Binomial Problem with n = 5, p(defect) = 7/15
-----
P(x = 2) = 5C2*(7/15)^2*(8/15)^3 = binompdf(5,7/15,2) = 0.3304
