Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
n C r= (n!)/(r!(n-r)!)

19 C 16 = (19!)/(16!*(19-16)!)

19 C 16 = (19!)/(16!*3!)

19 C 16 = (19*18*17*16!)/(16!*3!)

19 C 16 = (19*18*17)/(3!)

19 C 16 = (19*18*17)/(3*2*1)

19 C 16 = (5814)/(6)

19 C 16 = 969
