Union of Compound Events


In this lesson, you will learn about calculating the probability that any one of multiple mutually exclusive independent events will occur in a single experiment.If you think it through, it should make sense that the probability of pulling one Queen at random from a standard deck is  or , since there are 4 Queens in a standard 52 card deck. How then would you calculate the probability of pulling a Queen OR a King from the same deck?
