If P(A) = 0.3 and P(A ∩ B) = 0.03, find P(B|A).

1.	If P(A) = 0.3 and P(A ∩ B) = 0.03, find P(B\|A).
Answer» P(A) = 0.3, P(A ∩ B) = 0.03 are given. ∴ P(B\|A) =\( \frac{P(A∩B)}{P(A)} = \frac{0.03}{0.3} \)= 0.1

Answer»

P(A) = 0.3, P(A ∩ B) = 0.03 are given.

∴ P(B|A) =\( \frac{P(A∩B)}{P(A)} = \frac{0.03}{0.3} \)= 0.1
