An automobile manufacturer finds that 1 in every 2500 automobiles produced has a particular manufacturing defect.
(a) Use a binomial distribution to find the probability of finding 4 cars with the defect in a random sample of 6000 cars.
(b) The Poisson distribution can be used to approximate the binomial distribution for large values of n and small values of p. Repeat part (a) using a Poisson distribution and compare the results. |
