A manufacturer obtains clock-radios from three different subcontractors: 30% from A, 40% from B, and 30% from C. The defective rates for these subcontractors are 4%, 2%, and 5% 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.)
Sixteen cards are dealt from a deck of 52 cards. (a) What is the probability that the ace of spades is one of the 16 cards? (b) Suppose one of the 16 cards is chosen at random and found not to be the ace of spades. What is the probability that none of the 16 cards is the ace of spades? (c) Suppose the experiment in part(b) is repeated a total of 10 times (replacing the card looked at each...
Mathematics - Bayes Formula Jim Orson’s factory obtains capacitors from three different partners: 40% from A, 10% from B, and 50% from C. The defective rates for these partners are 3%, 3%, and 4% respectively. If a defective capacitor is returned, what is the probability that it came from partner A? From B? From C?

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...
A manufacturer of window frames knows from long experience that 10% of the production will have some type of minor defect that will require an adjustment. What is the probability that in a sample of 16 window frames: a. None will need adjustment? (Round the final answer to 3 decimal places.) Probability b. At least one will need adjustment? (Round the final answer to 3 decimal places.) Probability O c. More than two will need adjustment? (Round the final answer...
A manufacturer of window frames knows from long experience that 5% of the production will have some type of minor defect that will require an adjustment. What is the probability that in a sample of 20 window frames: a. None will need adjustment? (Round the final answer to 3 decimal places.) Probability b. At least one will need adjustment? (Round the final answer to 3 decimal places.) Probability c. More than two will need adjustment? (Round the final answer to...
A computer store sells three types of microcomputers, brand A, brand B, and brand C. Of the computers they sell, 60% are brand A, 20% are brand B, and 20% are brand C. They have found that 15% of the brand A computers, 15% of the brand B computers, and 10% of brand C computers are returned for service during the warranty period. If a computer is returned for service during the warranty period, what is the probability that it...
