Best ResponseYou've already chosen the best response.0permutation formula nPr = n!/(nr)! where n is total object taken, and r= objects taken at a time proof: nPr =n!/(nr)! 2P2= 2!/(22)! = 2!/0! = 2 where 2 is even

Best ResponseYou've already chosen the best response.0Sorry back, ye what watchmath said, logically it makes sense since you need a even number of transpositions to compose a even permutation, but i wasn't sure of the generic proof.
