A teacher has ordered four laptops for his students. Those laptops were dropped during the shipment process to the school and and classified as containing either, a no, a minor or, a major defect. Previously, 20% of the dropped laptops had no defect, 30% had a minor defect and 50% had major defect. (Hint: The defect on the laptop occur independently). (d) What is the joint probability of the number of laptops with a minor defect, and a major defect? (h) The conditional probability distribution of the number of laptops with major defects given that two laptops have minor defects? (i) The conditional mean of the number of laptops with major defects given that two laptops have minor defects?
