Answer 2

The notation which is the most appropriate notation when calculating conditional probabilities is:

B.
`P(C|D)=(P(C\bigcap D))/(P(D))`

Explanation:

In statistics, the conditional probability is defined as the probability of an event given that the other event has already occurred.

i.e. if C and D are two events such that the event D has already occurred then the conditional probability of C given D is given by:

`P(C|D)=(P(C\bigcap D))/(P(D))`

Hence, option: B is the correct answer.
