Venn Diagrams

A

and

B

are two independent events, then

P(A%20%5Ccap%20B)%3DP(A)%20%5Ccdot%20P(B)

Also, if

A

and

B

are independent then A' and B' are also independent.

%5Ctherefore%20P%5Cleft(A'%20%5Ccap%20B'%5Cright)%20%3DP%5Cleft(A'%5Cright)%20%5Ccdot%20P%5Cleft(B'%5Cright)

%3D(1-P(A))(1-P(B))

Again, if

A

and

B

are mutually exclusive, then

P(A%20%5Ccap%20B)%3D0
