The probability of pulling an ace or king from a deck of cards is?
To determine the probability of pulling an ace or king from a deck of cards, we need to first understand the total number of favorable outcomes (aces and kings) and the total number of possible outcomes (total number of cards in a deck).
Step 1: Find the number of favorable outcomes:
There are 4 aces and 4 kings in a standard deck of 52 cards. So the number of favorable outcomes is 4 (number of aces) + 4 (number of kings) = 8.
Step 2: Find the total number of possible outcomes:
In a standard deck of 52 cards, there are four suits (hearts, diamonds, clubs, and spades) with 13 cards each. So the total number of cards is 4 suits x 13 cards = 52.
Step 3: Calculate the probability:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 8 / 52 ≈ 0.154.
Therefore, the probability of pulling an ace or king from a deck of cards is approximately 0.154, or 15.4%.
