The question provides the following information. != means not equal to
P(A) != 0
P(B) != 0
P(A U B) = P(A) + P(B) - 0.1
P(A|B) = 0.2
I've calculated the following as previous parts of the question
P(AB) = 0.1
P(A'|B) = 0.8
P(B) = 0.5
The current part asks for P(A'). I've stared at this for a bit, and I don't know how to start. Any ideas? Thanks.
