Final answer:
There are 4 choices available for each card - an ace, a king, a queen, and a jack.
Step-by-step explanation:
In a standard deck of playing cards, there are 13 cards in each of the four suits - clubs, diamonds, hearts, and spades. The event described in the question involves choosing one card from each of the four suits and specifically selecting an ace, a king, a queen, and a jack.
To calculate the number of choices available for each card, we simply consider the number of cards of the desired rank in each suit. There is 1 ace, 1 king, 1 queen, and 1 jack in each suit, so there are 4 choices available for each card.
