if two events a and b are mutually exclusive what is the probability that a or b occurs?
248327
The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B) = 0.

are called mutually exclusive. These are events that cannot occur at the same time. When two events, A and B, are mutually exclusive, the probability of A and B, P(A∩B) = 0.

A and B are two events. If A and B are independent, then the probability that events A and B both occur is: p(A and B) = p(A) x p(B).

Probability of A or B (1 of 3) If events A and B are mutually exclusive, then the probability of A or B is simply: p(A or B) = p(A) + p(B).

If two events are mutually exclusive, they are as dependent as two events can be. Take example of a coin. ... (EDIT: The above statements are True only if probabilities of two events are non-zero. If one of the probability is zero, then events are mutually exclusive and independent. )

Two events are mutually exclusive if they cannot occur at the same time (i.e., they have no outcomes in common). In the Venn Diagram above, the probabilities of events A and B are represented by two disjoint sets (i.e., they have no elements in common).

= 0. The probability that Events A or B occur is the probability of the union of A and B. The probability of the union of Events A and B is denoted by P(A ∪ B) . If the occurrence of Event A changes the probability of Event B, then Events A and B are dependent.

Mutually Exclusive Events If two events are disjoint, then the probability of them both occurring at the same time is 0. If two events are mutually exclusive, then the probability of either occurring is the sum of the probabilities of each occurring.

Two events are mutually exclusive if the probability that they both happen at the same time is zero. If events A and B are mutually exclusive, then P(A AND B) = 0.
157489
A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes and P(A AND B) = 0. For example, suppose the sample space S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

Mutually exclusive events will have a probability of zero. All inclusive events will have a zero opposite the intersection. All inclusive means that there is nothing outside of those two events: P(A or B) = 1.

- P(A and B) = 0 if two events are mutually exclusive, then the probability of either occurring is the same of the probabilities of each occurring. - If two events are mutually exclusive, they cannot be independent and vice versa.

Two events are mutually exclusive or disjoint if they cannot occur at the same time. ... If Events A and B are mutually exclusive, P(A ∩ B) = 0. The probability that Events A or B occur is the probability of the union of A and B.

Two events are mutually exclusive if they cannot occur at the same time. Another word that means mutually exclusive is disjoint. ... If two events are mutually exclusive, then the probability of either occurring is the sum of the probabilities of each occurring.

Mutually Exclusive Events. When two events, A and B, are mutually exclusive, it means that they cannot both occur at the same time. This would mean that the joint probability of A and B, as well as the conditional probabilities for A and B, are equal to 0.

Addition Rule 1: When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event. ... The probability that A or B will occur is the sum of the probability of each event, minus the probability of the overlap. P(A or B)

Two Mutually Exclusive Events Two events are mutually exclusive if they cannot occur at the same time. The two sets E1 and E2 have no elements in common and their intersection is an empty set since they cannot occur at the same time.
