Since the probability of having a severe accident is 10% in any given year, the factory might expect to experience one accident every 10 years.
Probability refers to the likelihood of an event occurring from many possible outcomes.
Probability shows the ratio or percentage of an outcome happening.
Probability is always stated as a proportion of an occurrence.
The probability of a severe accident = 10%
The number of years when an accident should be expected = 100/10 = 10 years
In 10 years, when an accident might occur = 1 times (10 x 10%).
Thus, under probability, the factory might expect to experience one accident every 10 years.
