Explanation:
An usual event is one that has a low chance of occurring. Statisticians set cutoff points to separate unusual events from not too unusual events. The cutoff point that we usually use is 5% or 0.05. However this cutoff point is not set in stone. It depends on the researcher (hence it's subjective) and on the context or situation.
