i've been asked to state whether the events A and B are mutually exclusive or not I know that if AnB=0 they are mutually exclusive but I don't understand the test on how to calculate mutually exclusive.
- P(A) = 4/8
- P(B) = 4/8
- P(AnB) = 2/8
- P(AuB) = 6/8
I found that my P(A) + P(B)- P(AnB) was equal to the P(AuB) (4/8) + (4/8) - (2/8) = 6/8 P(AuB) but does this mean they are not mutually exclusive since this test is only applicable if the events are not mutually exclusive? otherwise can you please give me another way to test for mutually excluse
