What is P a B if A and B are mutually exclusive?

If two events are mutually exclusive then the probability of both the events occurring at the same time is equal to zero. P(A and B) = 0.

What is a ∩ B if events A and B are mutually exclusive?

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.

What is the value of P if A and B are mutually exclusive?

If A and B are mutually exclusive, then P(A∩B)=0. P ( A ∩ B ) = 0.

How do you find P AUB mutually exclusive?

If two events, A and B are mutually exclusive then, P(A U B) = P(A) + P(B). This follows immediately from (3). Since A and B are mutually exclusive, n(A ∩ B)=0 and so P(A ∩ B)=0.
