Conditioning on event B restricts the sample space to only the outcomes contained within B. Within this newly restricted space, the favorable outcomes for event A are located exclusively in the intersection of A and B ($A \cap B$).

Conditions: Event B has occurred.; We are calculating the conditional probability of A given B.
