The correct answer is: C. P(AB) / P(A)
The conditional probability of A given B, i.e., P (A/B), is the probability of event A occurring given that event B has already occurred. It is calculated as follows:
P(A/B) = P(AB) / P(B)
where P(AB) is the probability of both events A and B occurring, and P(B) is the probability of event B occurring.
Option A is incorrect because it is the conditional probability of B given A.
Option B is incorrect because it is the probability of event B occurring.
Option D is incorrect because it is the probability of both events A and B occurring.
