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 nothing. (Type an integer or decimal rounded to four decimal places as needed.)

2. A major home appliances company produces compressors for their refrigerators in one of their plants. The most critical part of a compressor is called crank which is made from cast iron. The surface quality of the crank directly affects the energy consumption and the noise level of the refrigerator Therefore, it has utmost importance in the compressor production. The process of crank manufacturing starts with sand casting process. Casting department is a separate building only dedicated to casting and...
