Final answer:
The probability of drawing a king or queen from a standard deck is 8 out of 52 cards, which simplifies to 2 out of 13, or approximately 15.38%.
Step-by-step explanation:
To find the probability that you draw a king or queen from a standard deck of playing cards, we need to consider the number of kings and queens in the deck relative to the total number of cards. There are 4 kings and 4 queens in a standard 52-card deck, so 8 cards total that fulfill our condition.
The probability of drawing a king or a queen is calculated by dividing the number of favorable outcomes by the total number of possible outcomes:
Probability = Number of kings or queens / Total number of cards = 8 / 52 = 2 / 13 ≈ 0.1538 or 15.38%
So, there is a 15.38% chance of drawing a king or a queen from a standard deck of cards.
