In a hand at Whist, what is the probability that four kings are held by a specified player?

Explanation

To solve the problem of finding the probability that a specified player holds all four kings in a hand at Whist, we can follow these steps:

### Step 1: Understand the total number of cards and players
In a standard deck, there are 52 cards, and in the game of Whist, there are 4 players, each receiving 13 cards.

### Step 2: Calculate the total number of ways to choose 13 cards from 52
The total number of ways to choose 13 cards from a deck of 52 cards is given by the combination formula \( \binom{n}{r} \), where \( n \) is the total number of items to choose from, and \( r \) is the number of items to choose. Thus, we calculate:
