1. The problem statement, all variables and given/known data Of the items produced daily by a factory, 40% come from line I and 60% from line II. Line I has a defect rate of 8%, whereas line II has a defect rate of 10%. If an item is chosen at random from the day’s production, find the probability that it will not be defective. 2. Relevant equations 3. The attempt at a solution My answer is 0.82 because Line I with no defect is 0.32+Line II with no defect is 0.50. OR 1-Both lines defected (0.18)=0.82. Is my approach correct?
