Misc 12 If P(A|B) > P(A), then which of the following is correct : (A) P(B|A) < P(B) (B) P(A โˆฉ B) < P(A) . P(B) (C) P(B|A) > P(B) (D) P(B|A) = P(B) Given P(A|B) > P(A) (๐‘ƒ(๐ด โˆฉ ๐ต))/(๐‘ƒ(๐ต))>"P(A") P(A โˆฉ B) > P(A) . P(B) Finding P(B|A) P(B|A) = (๐‘ƒ(๐ด โˆฉ ๐ต))/(๐‘ƒ(๐ด)) From (1) P(A โˆฉ B) > P(A) . P(B) Dividing by P(A) both sides (๐‘ƒ(๐ด โˆฉ ๐ต))/(๐‘ƒ(๐ด))>(๐‘ƒ(๐ด). ๐‘ƒ(๐ต))/(๐‘ƒ(๐ด)) P(B|A) > P(B) So, C is the correct answer.
