In any given year, a factory has a 20% probability of having an accident. About every how many years might the factory expect to have an accident?

Every 1 year

Every 2 years

Every 5 years

Every 20 years

Probability of having an accident = 20% o 0.2

Thus,

Expected number of years = 1/probability of accident = 1/0.2 = 5

Hence,

3.    Every 5 years  is the correct option.
