Hey, as title says...
have people been pre-learning other modules etc? or just brushing up their knowledge on the past two ... how about for english? whats everyone beeeenn up to!!!
so i know n!= n(n-1)(n-2)....3x2x1
so is (n-1)!=(n-1)(n-2)(n-3)...3x2x1
and (n-2)!=(n-2)(n-3)...3x2x1
how do you do this question :\ im getting a bit confused
nC2 + nC3 =220
i knwo itll be n!/2!(n-2)! + n/3!(n-3)!=220
can i get clarification on what the common denominator would be???
is it...
