For example, in geometry, two angles are said to be complementary when they add up to 90°. They are also considered as exhaustive events since the sum of their probabilities must be 1. • Complement of an event - suppose A is an event in the universal set U, the complement of A ("not A") consists of all the outcomes in U that are not in A. Hence option (A) is the answer. So the Complement of an event is all the other outcomes (not the ones we want). In the end, you will be able to calculate the probability of almost any typical event, as long as it is not beyond the scope of this text.

View a Panopto recording of textbook author Daren Starnes detailing ten reasons the new fourth edition of The Practice of Statistics is the right choice for the AP* Statistics course. If A is a set, then the absolute complement of A (or simply the complement of A) is the set of elements not in A (within a larger set that is implicitly defined). Therefore, the probability of getting a blue marble is 4/7. Found insideProbability is the bedrock of machine learning. The complement of an event \(A\) in a sample space \(S\), denoted \(A^c\), is the collection of all outcomes in \(S\) that are not elements of the set \(A\). Then, (not E) is the event it will rain in the evening The complementary event ${A}^{c}$ to an event A is the event 'A does not occur'.
