Webb7 dec. 2024 · P(B A) = P(B) Conditional Probability for Mutually Exclusive Events. In probability theory, mutually exclusive events are events that cannot occur simultaneously. In other words, if one event has already occurred, another can event cannot occur. Thus, the conditional probability of mutually exclusive events is always zero.

WebbIn science, the probability of an event is a number that indicates how likely the event is to occur. It is expressed as a number in the range from 0 and 1, or, using percentage …

WebbIn general, the probability of the union of two events is P [ B ⋃ C] = P [ B] + P [ C] − P [ B ⋂ C] . Hence, for mutually exclusive events holds P [ ⋃ 1 n A i] = ∑ 1 n P [ A i]. Knowing this, you can apply it to your tasks: a) P [ A ⋃ B] = P [ A] + P [ B] = 0.3 + 0.5 = 0.8 b) Occurence of A implies no occurence of B P [ A] = 0.3 WebbThe conditional probability of A to occur given that B occurs certainly is the probability that both A and B occur, divided by the probability that B occurs in the first place. In some cases, the occurrence of one event has no effect on the outcome of another. These events are called independent.
