Suppose that a single card is selected from a standard 52-card deck, such as the one shown in Figure 9.

(a) Compute the probability of the event E = “drawing a king.”

(b) Compute the probability of the event E = “drawing a king” or F = “drawing a queen” or G = “drawing a jack.”

Approach Use the classical method for computing the probabilities because the outcomes are equally likely and easy to count. Use the Addition Rule for Disjoint Events to compute the probability in part (b) because the events are mutually exclusive. For example, you cannot simultaneously draw a king and a queen.
