A bridge hand consists of any 13 cards selected from a 52car

A bridge hand consists of any 13 cards selected from a 52-card deck without regard to order. How many different bridge hands are there? (No scientific notation, I want the exact value)

Solution

bridge hands consist of 13 cards among 52 cards

if we need to find completely different bridge hands it will be 4 as 52/13 = 4

and these 4 can be arranged in 4! ways

hence total different will be 4*4! = 96

if we need to find the bridge hands with not completely differents means it can be different by one card, then it will be done by combination = 52C13 = 635013559600
