1. (30pts) Three subassemblies, A, B, and C are processed separately, each requiring two different operations. A is routed through operations 1 and 2, and B is routed through operations 3 and 4, and C is routed through operations 5 and 6. The three subassemblies are then joined in an assembly operation (operation 7). The seven operations have the following fraction defect rates: q₁ = 0.03,

q₂ = 0.08, q₃ = 0.05, q₄ = 0.09, q₅ = 0.01, q₆ = 0.04, q₇ = 0.07. If the desired final quantity of completed assemblies is 10,000 units, how many starting units of A, B and C will be required? There is no inspection or separation of defective units until after the final operation, so defective units and good units are processed together through all processing and assembly steps.
