Question

A card is drawn from a standard deck of 52 cards. What is the probability that it is a king or a queen?

Solution

1. There are 4 kings and 4 queens in the deck.
2. A card cannot be both a king and a queen, so the events are mutually exclusive.
3. Favorable cards = 4 + 4 = 8, so probability = 8/52 = 2/13.
