Refer to the table in the margin for n = 8 and p = 0.381. When a car buyer is selected at random, there is a 0.381 probability that he or she bought a used car (based on data from a CAA members' survey). In each case, assume that 8 buyers are randomly selected and find the indicated probability.

Find the probability that at least 5 car buyers bought used cars.
