Reserve Problems Chapter 5 Section 5 Problem 4 Four electronic ovens that were dropped during shipment are Inspeced and classified as containing either a major, a minor, or no defect. In the past, 60% of dropped ovens had a major defect, 30% had a minor defect, and 10% had no defect. Assume that the defects on the four ovens occur independently () What is the probability that, of the four dropped ovens, two have a major defect and two have...
