Independent Events Worksheets

What are Independent Events in Probability? Probability tells us the likelihood of an event taking place or not. It is represented between numbers 0 and 1, with 1 showing certainty and 0 representing impossibility of occurrence of an event. If the probability is a number closer to 1, it represents a higher likelihood of happening. However, if the number is closer to 0, then the event has fewer chances of taking place. In probability, the event is defined as the outcome of the experiment. These events can be classified as independent events. Independent events are those events that occur freely of each other. In other words, the incidence of one event doesn’t hinder or affect the occurrence of another event. For example, the outcomes of two rolling dies do not depend on each other. The outcome of one die doesn't affect or change the outcome of the second die. Two events are independent if one or more of the following are true. P(A|B) = P(A) P(B|A) = P(B) P(A ∩ B) = P(A) P(B)
