Question: 13. Items produced in assembly line A are defect free with probability 0.9, and those produced in assembly line B are defect free with probability
13. Items produced in assembly line A are defect free with probability 0.9, and those produced in assembly line B are defect free with probability 0.99. A sample of 200 items from line A and a sample of 1000 from line B are inspected.
(a) Give an approximation to the probability that the total number of defective items found is at most 35.
(Hint. See Example 5.4-3.)
(b) Use R commands similar to those used in Example 5.3-4 to find the exact probability of part (a).
