Employee training. A chain of car muffler and brake repair shops maintains a training program for its mechanics. All new mechanics begin training in muffler repairs. Every 3 months, the performance of each mechanic is reviewed. Past records indicate that after each quarterly review, 30 % of the muffler repair trainees are rated as qualified to repair mufflers and begin training in brake repairs. 20 % are terminated for unsatisfactory performance, and the remainder continue as muffler repair trainees. Also, 30 % of the brake repair trainees are rated as fully qualified mechanics requiring no further training. 10 % are terminated for unsatisfactory performance, and the remainder continue as brake repair trainees. (A) In the long run, what percentage of muffler repair trainees will become fully qualified mechanics? (B) In the long run, what percentage of brake repair trainees will be terminated? (C) What is the average number of quarters that a muffler repair trainee will remain in the training program before being either terminated or promoted to fully qualified mechanic?
