Question

Suppose that a single card is selected from a standard​ 52-card deck. What is the probability that the card drawn is a kingking​? Now suppose that a single card is drawn from a standard​ 52-card deck, but it is told that the card is court (jack comma queen comma or king )court (jack, queen, or king). What is the probability that the card drawn is a kingking​?

Answer 1

Title:

See the explanation.

Step-by-step explanation:

Total number of cards in a deck is 52.

From these 52 cards 1 can be drawn in 52 ways.

1 king from total 4 kings can be selected in 4 ways.

The probability of getting a king is $\frac{4}{52} = \frac{1}{13}$.

Now, in total there are 12 courts.

1 court can be selected in 12 ways.

Since there is 4 kings, the probability of the card drawn from courts be a king is $\frac{4}{12} = \frac{1}{3}$.
