Question: Suppose that A1, A2 , A3 , and B are events where A1 , A2 , and A3 are mutually exclusive and P (A1) =.2

Suppose that A1, A2 , A3 , and B are events where A1 , A2 , and A3 are mutually exclusive and
P (A1) =.2 P (A2) =.5 P (A3) = .3
P (B A1) = .02 P (B A2) =.05 P( B A3 )=.04
Use this information to find P (A1 B), P (A2 B) and P( A3 B).
