The following diagram shows the formula for conditional probability. Scroll down the page for more examples and solutions on finding the conditional probability.

A conditional probability is a probability that a certain event will occur given some knowledge about the outcome or some other event. The concept of conditional probability is closely tied to the concepts of …

Nov 18, 2025 · To find the probability that a student plays football given that they play basketball, we use the conditional probability formula: P (A|B) = n (A ∩ B) / n (B)

The equation P (A and B) = P (A ∣ B) × P (B) might seem confusing at first, but it's essentially saying that the probability of both events A and B happening is the probability of event A happening given that …

The conditional probability is the probability of happening of an event of A given that another event B has already occurred. Understand conditional probability and also the probability of independent …

Use the conditional probability calculator to determine the probability of an event conditional on another event.

Nov 17, 2025 · The probability that an event A will occur given another event B occurs is written as P (A | B), meaning “the probability of A given B.” Assuming that the probability of B is not zero, this can be …
