QUESTION 5 A small assembly plant has 100 employees. Each worker is expected to complete work assignments on time and in such a way that the assembled product will pass a final inspection. On occasions, some of the workers fail to meet the performance standards by completing work late and/or assembling a defective product. At the end of a performance evaluation period, the production manager found that 10 workers had completed work late, 20 workers had assembled a defective product, and 8 workers had both completed work late and assembled a defective product. 1. What is the probability that a worker chosen at random had completed work late? 2. What is the probability that a worker chosen at random had assembled a defective product? 8. What is the probability that a worker chosen at random had completed work late and assembled a defective product? 4. What is the probability that a worker chosen at random had completed work late or assembled a defective product?
