What is the probability of drawing a king or a queen in a shuffled deck of cards
In a standard deck of 52 cards, there are 4 kings and 4 queens.
The probability of drawing a king or a queen can be calculated as follows:
Number of kings = 4
Number of queens = 4
Total number of kings and queens = 4 + 4 = 8
Total number of cards in a deck = 52
Probability of drawing a king or a queen = (Total number of kings and queens) / (Total number of cards in a deck) = 8/52 = 2/13
Therefore, the probability of drawing a king or a queen in a shuffled deck of cards is 2/13, or approximately 0.1538.
