Probability of "either/or" and "neither" for two independent events

WebbSo, the probability of rolling an even number on a die is 3∕6 = 1∕2. Since the five dice are independent events, we can multiply their probabilities together, so the probability that all five dice show even numbers is (1∕2)⁵ = 1∕32. Webb17 maj 2024 · 1. What you're looking for is known as conditional probability. In general, the probability of A given B, written P ( A B), is given by. P ( A B) = P ( A ∩ B) P ( B) Intuitively, you can interpret this as once B occurs, we are in the world of B, so our new overall probability is P ( B).
