Charlestown Electric Company is building a new generator for its Mt. Washington plant. Even with good maintenance procedures, the generator will periodically fail or break down. Historical figures for similar generators indicate the following relative frequency of failures during a year:

Assume the useful lifetime of the generator is 25 years. Use simulation to estimate the number of breakdowns that will occur in the 25 years of operation. Is it common to have five or more consecutive years of operation without a failure?
