Complement of an Event Worksheets
What is a Complement of an Event? When developing probability concepts, it is essential to understand all terms and phrases that are frequently used in probability problems. Events, sample space, outcomes, order, and complement of an event. Complement is a term that is not only used in probability but is also part of the concept of sets. Whether the term is being used in sets or probability, it holds the same meaning. When you are asked to use a complement of the set, it means all elements that are not part of the set. In probability, when we talk about the complement of an event, it includes all outcomes other than the required or desired outcomes. If we write a probability of the desired event we use the following symbols; P(A) and to denote a complement of the event, we write P(A'). When you add these two elements, the result is 1.
