Probability of Drawing a Card with an Even Number

The probability of randomly drawing a card with an even number from a standard deck of 52 playing cards can be calculated using the total number of even-numbered cards and the total number of cards in the deck.

In a standard deck of 52 playing cards, there are: - 26 red cards - 26 black cards - 13 cards in each suit (hearts, diamonds, clubs, spades) - 2 red and 2 black cards for each number (2, 4, 6, 8, 10) and face card (Jack, Queen, King)

To calculate the probability of drawing a card with an even number, we can use the following formula: \[ \text{Probability} = \frac{\text{Number of even-numbered cards}}{\text{Total number of cards}} \]

Calculation of Probability

The total number of even-numbered cards in a standard deck of 52 playing cards is 20 (2, 4, 6, 8, 10 for each suit).

The total number of cards in the deck is 52.

Using the formula, the probability of randomly drawing a card with an even number can be calculated as: \[ \text{Probability} = \frac{20}{52} = \frac{5}{13} \]

So, the probability of randomly drawing a card with an even number from a standard deck of 52 playing cards is 5/13.
