In a hand at whist, what is the chance that the four kings are held by a specific player?

Please Explain.

In a game of whist, four players are dealt with 13 cards.
A hand of a specific player can  contains all 4 kings and other 9 cards.
So 4 kings are chosen from 4 kings, and other 9 cards are chosen from 48 cards.
Hence number of ways ⁴C₄ * ⁴⁸C₉
And the total number of ways 13 cards are dealt to a player  is ⁵²C₁₃
So probability = (⁴C₄ * ⁴⁸C₉ )/ ⁵²C₁₃
= 0.002641 (Ans)
