There are 4 Queens, 4 Kings, and 4 Aces in a standard deck of cards.
Add these together, and there are 12 cards that you have a chance of choosing from.
The ratio of cards we want to get (queen, king ace) to number of cards is 12/52. This is the probability. We can simplify it further by dividing both sides by 4. We now have the fraction 3/13.
Therefore, the probability of drawing a queen, king, or ace is 3 in 13, or 23%.
