(n!)/(r!(n-r)!)

(15!)/(7!*(15-7)!)

(15!)/(7!*8!)

(15*14*13*12*11*10*9*8!)/(7!*8!)

(15*14*13*12*11*10*9)/(7!)

(15*14*13*12*11*10*9)/(7*6*5*4*3*2*1)

(32432400)/(5040)

6435


So 15 C 7 = 6435

by definition



Now does anything divide out from the top and bottom?(numerator and denominator)

And now is there any common factors we can divide out? (for example 14=2*7 and we have a 7 in the denominator so we can cancel a 7 from both those numbers)
