4. What is the probability of selecting either a King or a Queen if one card is drawn from a standard 52 card deck?

To find the probability of selecting either a King or a Queen when drawing one card from a standard 52-card deck, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.

Number of favorable outcomes:
- There are 4 Kings (King of Hearts, King of Diamonds, King of Clubs, King of Spades).
- There are also 4 Queens (Queen of Hearts, Queen of Diamonds, Queen of Clubs, Queen of Spades).

Total number of possible outcomes:
- A standard deck of playing cards consists of 52 cards, so there are 52 possible outcomes.

Therefore, the probability of selecting either a King or a Queen is (4 Kings + 4 Queens) / 52 = 8 / 52 = 2 / 13, which simplifies to approximately 0.154 or 15.4%.

To find the probability of selecting either a King or a Queen from a standard 52-card deck, we first need to determine the number of favorable outcomes (cards that meet the criteria) and the total number of possible outcomes (total cards in the deck).

There are 4 Kings and 4 Queens in a standard deck - one of each for each of the four suits (hearts, diamonds, clubs, and spades). So, there are a total of 8 favorable outcomes (4 Kings + 4 Queens).

Now, let's calculate the total number of possible outcomes. In a standard deck, there are 52 cards in total.

So, the probability of selecting either a King or a Queen can be found by dividing the number of favorable outcomes by the total number of possible outcomes:

Probability = Favorable Outcomes / Total Outcomes

Probability = 8 / 52

Simplifying this fraction, we get:

Probability = 2 / 13

Therefore, the probability of selecting either a King or a Queen when drawing one card from a standard 52-card deck is 2/13.

There are 4 kings and 4 queens in a 52 card deck.

(4+4)/52 = ?
