If events A and B are in the same sample space:(adsbygoogle = window.adsbygoogle || []).push({});

Proove that if P(A I B') > P(A) then P(B I A) < P(B)

- .

(where B' is the Probability of A given not B)

Proove that if P(A I B) = P(A) then P(B I A) = P(B)

- .

do we assume independence here so that P(A I B) = [P(A)*P(B)]/ P(B) = P(A) and state that since P(A n B) = P(B n A) that P(B I A) = [P(B)*P(A)] / P(A) = P(B) or is it wrong to assume independence here?
