A subassembly of electronic components, called M1, consists of 5 parts that can fail. Three parts have failure probabilities of 0.03. The other two parts have failure probabilities of 0.02. Each M1 can only be tested after assembly into the parent VCR. It takes a week to get M1 units (the lead time is one week), and the company has orders for the next five days of 32,44,36,54, and 41. How many M1 units should be on hand right now so that all orders can be filled?
