What Is The Difference Between Independent And Dependent Events

Two events are independent if the result of the second event is not affected by the result of the first event.

Dependent events means that one event has had an effect on the other. The concept of dependent events gives rise to the concept of conditional probability. Imagine a single event. Independent events do not affect one another and do not increase or decrease the probability of another event happening.

A dependent variable is the variable being tested and measured in a scientific experiment. Thus one event depends on another so they are dependent. For instance if we look at the probability of someone going to the shops and. Independent and dependent events.

Otherwise they are said to be dependent events. If the occurrence or non occurrence of e1 does not affect the probability of occurrence of e2 then p e2 e1 p e2 and e1 and e2 are said to be independent events. Being able to tell the difference between a dependent and independent event is vitally important in solving probability questions. If a and b are independent events the probability of both events occurring is the product of the probabilities of the individual events.

Two events are said to be independent events if the two events have no effect on one another. Dependent events influence the probability of other events or their probability of occurring is affected by other events. So winning the lotto and buying a ticket are dependent events. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.

Two or more events are dependent if the outcome of one event affects the outcome of the other s. Otherwise they are said to be dependent events. The dependent variable is dependent on the independent variable. That depends upon you buying a ticket.

Independent events can exist in reality.
