Question 12 If A and B are two events such that P(A) = 0.4, P(B) = 0.8 and P(B|A) = 0.6, then find P(A|B) P(A) = 0.4 , P(B) = 0.8 & P(B|A) = 0.6 Now, we know that P(B|A) = (๐(๐ต โฉ ๐ด))/(๐(๐ด)) 0.6 = (๐(๐ด โฉ ๐ต))/(๐(๐ด)) 0.6 = (๐(๐ด โฉ ๐ต))/(0. 4) P(A โฉ B) = 0.6 ร 0.4 P(A โฉ B) = 0.24 โด P(A โฉ B) = 0.32 P(A|B) = (๐(๐ด โฉ ๐ต))/(๐(๐ต)) = 0.24/0.8 = 24/80 = 3/10 = 0.3 โด P(A|B) = 0.3
