If A and B are two events and A ≠ Φ, B ≠ Φ, then
A. P(A|B) = P(A. . P(b)
B. P(A|B. = \(\frac{P(A \cap B)}{P(B)}\)
C. P(A|B) . P(B|A) = 1
D. P(A|B) = P(A)|P(b)
Answer:B
If A and B are two events and A ≠ Φ, B ≠ Φ, then
A. P(A|B) = P(A. . P(b) B. P(A|B. = \(\frac{P(A \cap B)}{P(B)}\) C. P(A|B) . P(B|A) = 1 D. P(A|B) = P(A)|P(b)
