To restate the Addition Rule of Probability: P(A ∪ B) = P(A) + P(B) − P(A ∩ B) Remember that probability is simply the proportion of the objects we are interested in relative to the total number of objects. Web10 de mar. de 2024 · The closer the probability is to zero, the less likely it is to happen, and the closer the probability is to one, the more likely it is to happen. The total of all the probabilities for an event is equal to one. For example, you know there's a one in two chance of tossing heads on a coin, so the probability is 50%.
