If A and B are two mutually exclusive events such that P(A) = (1/2) and P(B) = (1/3), find P(A or B).

Given : A and B are mutually exclusive events

P(A) = , P(B) =

To find : P(A or B)

Formula used : P(A or B) = P(A) + P(B) - P(A and B)

For mutually exclusive events A and B, P(A and B) = 0

Substituting in the above formula we get,

P(A or B) = + – 0

P(A or B) =

P(A or B) =
