Question:

A sample of size n is selected from a large lot of shear drill bits. Suppose that a proportion p1 contains exactly one defect and a proportion p2 contains more than one defect (with p1 + p2 < 1 ). The cost of replacing or repairing the defective drill bits is C = 4Y1 + Y, where Y1 denotes the number of bits with one defect and Y2 denotes the number with two or more defects. Find the expected value of C.
