The quality-control inspector of a production plant will reject a batch of syringes if two or more defective syringes are found in a random sample of twelve syringes taken from the batch. Suppose the batch contains 1% defective syringes. (a) Make a histogram showing the probabilities ofr = 0, 1, 2, 3, ..., 11 and 12 defective syringes in a random sample of twelve syringes.

(Enter a number. Enter your answer to two decimal places.) What is the expected number of defective syringes the inspector will nd? (Enter a number. Enter your answer to two decimal places.) (c) What is syri n gas the probability that the batch will be accepted? (Enter a number. Round your answer to three decimal places.) (d) Find a (in terms of the number of syringes). (Enter a number. Round your answer to three decimal places.) 0': syringes
