# What is a simple event in probability? What is a complementary event?

See explanation.

A elementary event is (exactly speaking) a primary oobject which is not defined (as for example a point or a number).

A simple event in probability refers to an outcome or event that cannot be further broken down into simpler events. It is the most basic unit of probability analysis.

A complementary event in probability is the event that consists of all outcomes that are not part of the given event. In other words, if ( A ) is an event, then the complementary event of ( A ) is denoted by ( A' ) or ( A^c ), and it includes all outcomes that are not in ( A ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
