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}. How to Find Probability of an Event?

We will extend the above ideas to the situation where we have three sets, which we will denote A, B, and C. We will not assume anything more than this, so there is the possibility that the sets have a non-empty intersection. The goal will be to calculate the probability of the union of these three sets, or P (A U B U C). … Visa mer To see the formula for the probability of the union of three sets, suppose we are playing a board game that involves rolling two dice.
