Katie is playing a game using a 26-card deck that contains the black suits of the cards, which are 13 clubs and 13 spades. She c
Vladimir [108]

Answer:

The probability that Katie will draw a face card on her next turn is 3/13, or approximately 23%.

Step-by-step explanation:

In a regular deck, there are four suits (clubs, spades, hearts and diamonds).  Each suit has 13 cards that go from 2 - 10 plus the Ace, King, Queen and Jack.  Since Katie is playing using a 26-card deck of only two suits, then there are only two kings, two queens and two jacks in the entire deck.  In order to find probability, we form a fraction where the denominator is the total number of outcomes, in this case 26, and the numerator is the number of desired outcomes, in this case the total number of face cards in the deck - 6.  So, the probability that Katie will choose a face card on the next turn is 6/26, which simplifies to 3/13 in lowest terms.
