Answer 1

C 25,10 =  25x24x23....x15! =   25*24*23*22*21*20*19*18*17*16*   15!    
                    10!(25-10)!                             10!*                         15! os 15! se anulam

c25,10 = 11861676288000/3628800

C25,10 = 3268760

agora avalie-me

Answer 2

Boa noite!

C(25,10)

C(n,p)=n!/(n-p)!p!

C(25,10)=25!/(25-10)!10!

C(25,10)=25!/15!10!

C(25,10)=25×24×23×22×21×20×19×18×17×16×15!/15!10!

C(25,10)=25×24×23×22×21×20×19×18×17/10!

C(25,10)=741354768000/10×9×8×7×6×5×4×3×2×1

C(25,10)=11861676288000/3628800 = 3268760
