Best ResponseYou've already chosen the best response.0permutation= order matters...and combination=order does matter. If you are writing a 4 digit number, order does matter because what goes in the first place will effect the second number, and the first and second will affect the 3rd..and so on. since there are no repeats therefore it is a permutation

Best ResponseYou've already chosen the best response.0actually it is not 10*9*8*7, the first digit may not be a 0 as that would be a 3 digit number, it is 9*9*8*7=4536
