if events a and b are mutually exclusive then events a or event b must occur?

If event A and event B cannot occur at the same time, then events A and B are said to be a) mutually exclusive. ... If either event A or event B must occur, then events A and B are said to be a) mutually exclusive.

If two events A and B are mutually exclusive, the events are called disjoint events. ... If the events A and B are not mutually exclusive, the probability is: (A or B) = p(A) + p(B) – p(A and B).

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)
463060
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. The probability that Events A or B occur is the probability of the union of A and B.

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.

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.

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. ... P(A AND B)=210 P ( A AND B ) = 2 10 and is not equal to zero.

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.

Answer and Explanation: Since these events are mutually exclusive, they cannot both occur, so P(A and B) = 0.

If two events have no elements in common (Their intersection is the empty set.), the events are called mutually exclusive. Thus, P(A∩B)=0 . This means that the probability of event A and event B happening is zero. They cannot both happen.

Events are mutually exclusive if the occurrence of one event excludes the occurrence of the other(s). Mutually exclusive events cannot happen at the same time. ... This of course means mutually exclusive events are not independent, and independent events cannot be mutually exclusive.

This makes sense because if A and B are mutually exclusive, then if A occurs, then B cannot also occur; and vice versa. ... Then if the two events are mutually exclusive, they can not be independent. If two events are independent, they cannot be mutually exclusive.

Mutually Exclusive Events Two events are mutually exclusive if they cannot occur at the same time. ... If two events are disjoint, then the probability of them both occurring at the same time is 0.

Mutually Exclusive Events 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.

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.

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 disjoint, then the probability of them both occurring at the same time is 0.
