Козырных карт 13. Не козырных дам 3. 13+3=16. 16/54=4/13

Answer 2

Probability of drawing a trump card or a queen from a deck of 52 playing cards

To calculate the probability of drawing either a trump card or a queen from a deck of 52 playing cards, we need to determine the number of favorable outcomes and the total number of possible outcomes.

1. Total number of possible outcomes: - In a standard deck of 52 playing cards, there are 4 suits (hearts, diamonds, clubs, and spades) and each suit contains 13 cards (Ace, 2-10, Jack, Queen, and King). - Therefore, the total number of possible outcomes is 52.

2. Number of favorable outcomes: - To calculate the number of favorable outcomes, we need to consider two cases: drawing a trump card and drawing a queen.

Case 1: Drawing a trump card: - In a standard deck of playing cards, there are 13 trump cards (Ace, 10, King, Queen, and Jack of the trump suit). - Therefore, the number of favorable outcomes for drawing a trump card is 13.

Case 2: Drawing a queen: - In a standard deck of playing cards, there are 4 queens (one queen in each suit: hearts, diamonds, clubs, and spades). - Therefore, the number of favorable outcomes for drawing a queen is 4.

3. Calculation of probability: - The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. - In this case, the probability of drawing either a trump card or a queen is given by:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

- For this scenario, the number of favorable outcomes is 13 (for drawing a trump card) + 4 (for drawing a queen), which equals 17. - The total number of possible outcomes is 52. - Therefore, the probability of drawing either a trump card or a queen is:

Probability = 17 / 52 ≈ 0.327 or 32.7%

So, the probability of drawing either a trump card or a queen from a deck of 52 playing cards is approximately 0.327 or 32.7%.
