The probability that a part produced by a certain factory''s assembly line will be defective is 0.009. Suppose a sample of 47 parts is taken. The probability that exactly 3 parts will be defective is nothing. (Round your answer to the nearest thousandth.) The probability that no more than 2 parts will be defective is nothing.

Step 1/2 a. To find the probability that the can was produced by line 1, we need to divide the number of nonconforming cans produced by line 1 by the total number of nonconforming cans produced by all three lines: P(line 1) = 500 / (500 + 400 + 600) = 500 / 1500 = 1/3 ≈ 0.333 To find the probability that the reason for nonconformance is a crack, we need to …
