Theorem hashbc 12613

Description: The binomial coefficient counts the number of subsets of a finite set of a given size. This is Metamath 100 proof #58 (formula for the number of combinations). (Contributed by Mario Carneiro, 13-Jul-2014.)

hashbc	|- ( ( A e. Fin /\ K e. ZZ ) -> ( ( # ` A ) _C K ) = ( # ` { x e. ~P A | ( # ` x ) = K } ) )

Distinct variable groups:   x, A   x, K

Proof of Theorem hashbc

Dummy variables j k w y z are mutually distinct and distinct from all other variables.
