a. P (B|A) = P (A and B) / P (A)

Step-by-step explanation:

The notation for conditional probability is P (B|A) and is defined as P (B|A) = P (A and B) / P (A) when the two events are not independent. When the events are independent we have that P (B|A) = P (B) which means that the occurence of B does not depent of the occurence of A. Another way of define independence of two events is to say that P (A and B) = P (A) P (B). Therefore, the answer is a. P (B|A) = P (A and B) / P (A)
