EXAMPLE 13.7-12 (Quality Control Problem) The output of a production line is checked by an inspector for one or more of three different types of defects, called defects A, B and C. If defect A occurs, the item is scrapped. If defect Bor Coccurs, the item must be reworked. The time required to rework a B defect is 15 minutes and the time required to rework a C defect is 30 minutes. The probabilities of an A, B and C defects are 0.75, 0.20 and 0.10 respectively. For ten items coming off the assembly line, determine the number of items without any defects, the number scrapped and the total minutes of rework time. Use the following random numbers: RN for defect 18 91 40 93 01 83 63 47 52 RN for defect B 17 36 57 04 79 35 10 1357 09 RN for defect 82 95 18 96 20 84 56 11 52 03 55 : B46
