In this post, we understand the notion of conditional probability and recognise and use language that indicates conditionality use the notation P(A|B) and the formula P(A|B) = \frac{P(A \cap B)}{P(B)}, P(B) \neq 0 . Conditional probability is the probability of A occurring, given that event B has already occurred.
