Probability of Independent Events - Concept

Concept Concept (1)

When calculating the probability of multiple events, we must determine whether the events are dependent or independent. The probability of independent events is slightly less complicated than calculating the probability of dependent events. When calculating the probability of independent events, unlike the probability of dependent events, we do not need to take into account the effect of one event occurring on the other.
