Question

Из стандартной колоды 36 карт наугад вытягивают одну карту какова вероятность того, что эта карта окажется королем любой масти, тузом любой масти или пиковой дамой

Answer 1

25%, вероятность 1 к 4 

К К К К

Т Т Т Т

(п) Д

4К +4Т + 1 (п)Д = 9

9/36 = 1/4 (25%) вероятность того что выпадет одна из этих карт, 

Answer 2

Calculating the Probability of Drawing Specific Cards from a Standard Deck

To calculate the probability of drawing a specific card from a standard deck of 36 cards, we can consider the total number of favorable outcomes and the total number of possible outcomes.

Total Number of Favorable Outcomes: - The favorable outcomes in this case are drawing a king of any suit, an ace of any suit, or the queen of spades.

Total Number of Possible Outcomes: - The total number of cards in a standard deck is 36.

Probability Calculation

The probability of an event is calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.

Probability of Drawing a King, Ace, or Queen of Spades: - The probability can be calculated as follows: - Number of favorable outcomes: 4 (kings) + 4 (aces) + 1 (queen of spades) = 9 - Total number of possible outcomes: 36

Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes

Probability = 9 / 36

Probability = 1 / 4

So, the probability of drawing a king of any suit, an ace of any suit, or the queen of spades from a standard deck of 36 cards is 1/4.
