Conditional Probability:

Conditional probability of an event is defined as the probability of an event given that another event is already occured, this can be represented as {eq}P(A|B) =\frac{P(A \cap B)}{P(B)} {/eq}

Conditional Probability is equal to unconditional probability if two events are independent.
