(Rylan's basketball team has
players. How many ways can
his coach choose five starting players?
C(n,r) = (n!)/(r!(n-r)!) C(11,5) = (11!)/(5!*(11-5)!) C(11,5) = (11!)/(5!*6!) C(11,5) = (11*10*9*8*7*6!)/(5!*6!) C(11,5) = (11*10*9*8*7)/(5!) C(11,5) = (11*10*9*8*7)/(5*4*3*2*1) C(11,5) = (55440)/(120) C(11,5) = 462
So there are 462 ways.
