Types of events in probability. html>eq
Probability is defined as a quantitative measure of uncertainty – a numerical value that conveys the strength of our belief in the occurrence of an event. An independent event is an occurrence that is not related to any other event. If there be no element common between two or more events, i. In this situation, P(A and B) = P(A)*P(B). Here, there is the chance of exactly one outcome. The number of times a value occurs in a sample is determined by its probability of occurrence. 11. The closer the probability is to 0, the less likely the event is to occur. An event is modeled as the set of those possible outcomes of an experiment which satisfy a property or proposition characterizing the event. Probability theory. Events can be: Independent (each event is not affected by other events), Dependent (also called "Conditional", where an event is affected by other events) Mutually Exclusive (events can't happen at the same time) Let's look at each of those types.
