The conditional probability formula is P(X|Y) = P (X ∩ Y) / P (Y). Then the correct option is A.
<h3>What is conditional probability?</h3>
Suppose that the sample space is S. Out of which there are two events, A and B, subsets of S.
Then, we can interpret P(A|B) as the probability of that part of A which is in B, with the new sample space as B. (assuming the probability of B is not 0).
Symbolically, we write it as:
P(A|B) = P(A ∩ B) / P(B)
Then we have
P(X|Y) = P(X ∩ Y) / P(Y)
Thus, the correct option is A.
