Webb14 dec. 2024 · For example, if the probability of A is 20% (0.2) and the probability of B is 30% (0.3), the probability of both happening is 0.2 × 0.3 = 0.06 = 6%. How do I calculate conditional probability? For events that happen completely separately and don't depend on each other, you can simply multiply their individual probabilities together . WebbThe union of events in probability is the same as the OR event. If there are two events that belong to this group then the outcomes of either event or both will be the result. The union symbol (∪) is used to denote the OR event. For example, A = {1, 2, 3, 4}, B = {2, 3, 5, 6} then A ∪ B = {1, 2, 3, 4, 5, 6}.
