Chapter , Problem 9(choose chapter or problem)
The profit is $350 for each computer assembled by a certain person. Suppose that the assembler guarantees his computers for one year and the time between two failures of a computer is exponential with mean 18 months. If it costs the assembler $40 to repair a failed computer, what is the expected profit per computer? Hint: Let N (t) be the number of times that the computer fails in [0, t]. Then $ N (t): t 0 % is a Poisson process with parameter = 1/18.
