WebJun 28, 2024 · Mathematics Conditional Probability. Conditional probability P (A B) indicates the probability of event ‘A’ happening given that event B happened. We can easily understand the above formula using the below diagram. Since B has already happened, the sample space reduces to B. So the probability of A happening becomes divided by P (B)
