suppose that for a particular piece of machinery, the frequency distribution of monthly breakdowns is as follows: number of breakdowns prob. 0 0.50 1 0.25 2 0.10 3 0.10 4 0.05 the cost of a breakdown is $2,000, and the cost of a preventive maintenance program is $2,000 per month. if the preventive maintenance program is adopted, the probability of a machine breakdown is negligible. how much better off per month would the firm be if it adopted preventive maintenance? multiple choice $100 better off $2,000 better off $200 better off $100 worse off $200 worse off
