A manufacturer obtains clock-radios from three different subcontractors: 10% from A, 40% from B, and 50% from C. The defective rates for these subcontractors are 4%, 3%, and 3% respectively. If a defective clock-radio is returned by a customer, what is the probability that it came from subcontractor A? From B? From C? The probability that it came from subcontractor Ais (Type a decimal. Round to three decimal places if needed.) The probability that it came from subcontractor Bis (Type...

7.6.15 Companies A, B, and C produce 20%, 40%, and 40%, respectively, of the major appliances sold in a certain area. In that area, 2% of the company A appliances, 4 and one half % of the company B appliances, and 4% of the company C appliances need service within the first year. Suppose a defective appliance is chosen at random; find the probability that it was manufactured by Company B. The probability that it came from company B is...

1) Three dice are rolled. If each lands on a different number, find the probability that one is 3? 2) ) Three machines (A, B, C) manufacture screws. They manufacture 25%, 35%, and 40% of the screws, respectively. The output screws are defective at 2%, 3%, and 5%, respectively. If you choose a random screw produced at the factory and it is defective, what is the probability it came from each machine A, B, and C

A company buys tires from three suppliers A, B and C. Supplier A has a record of delivering tires containing 8% defective, whereas supplier B has a defective rate of only 4% and supplier C has defective rate of 12%. Suppose 35% of current supply comes from supplier A, 30% from supplier C and rest from supplier B. If a tire is selected at random, find the probability: (a) that the tire is NOT defective; (b) given the selected tire...

6. A manufacturing firm orders computer chips from three different companies: 10% from Company A; 20% from Company B; and 70% from Company C. Some of the computer chips that are ordered are defective: 4% of chips from Company A are defective; 2% of chips from Company B are defective; and 0.5% of chips from Company C are defective. A worker at the manufacturing firm discovers that a randomly selected computer chip is defective. What is the probability that the...
