An eyeglass manufacturer knows from past experience that 16% of manufactured lenses are defective due to scratches. Suppose that the manufacturer examined seventeen eyeglasses. Assume that the binomial distribution applies. (a) What are the number of trials n and the probability of "success" p in this case? n = 17✓ , P = 0.16 0 Use technology to determine the following probabilities, rounding each to 4 decimal places. (b) Probability that none of the lenses selected have scratches. Answer = 5.16 X (c) Probability that all of the lenses selected have scratches. Answer = 0.1362 X
