Answer: The probability of drawing a Jack from a well-shuffled deck of 52 cards is 1/13.

To find the probability of drawing a Jack from a well-shuffled deck of 52 cards, we need to drive the total number of Jacks present in the deck by the total number of cards.

Total Number of Jacks: In a standard deck of playing cards, each suit (hearts, diamonds, clubs, and spades) contains one Jack.
So, there are a total of 1 × 4 = 4 Jacks are there in the deck.

Total Number of Cards in the Deck: A standard deck contains 52 cards.

Now, we can calculate the probability of getting a Jack:

Probability of getting a Jack = Total number of cards / Number of Jacks = 4/52​

Simplify the fraction:

Probability of getting a Jack = 1/13​

Therefore, the probability of getting a Jack from a well-shuffled deck is 1/13​.
