Best ResponseYou've already chosen the best response.1Are you familiar with the permutation formula?

Best ResponseYou've already chosen the best response.1If not, the permutation formula is n P r = (n!)/((nr)!) where n! means n! = n*(n1)*(n2)*...*3*2*1 For example: 6! = 6*5*4*3*2*1

Best ResponseYou've already chosen the best response.1So in our case, 10 P 6 is 10 P 6 = (10!)/((106)!) since n = 10 and r = 6

Best ResponseYou've already chosen the best response.1(10!)/((106)!) will become (10!)/(4!) since 106 = 4

Best ResponseYou've already chosen the best response.1Then you expand out 10! like so 10*9*8*7*6*5*4! We stop at 4 because the "4!" terms will cancel So (10!)/(4!) turns into (10*9*8*7*6*5*4!)/(4!) and the "4!" terms will cancel leaving us with 10*9*8*7*6*5

Best ResponseYou've already chosen the best response.1Last step is to multiply out 10*9*8*7*6*5 to get your answer
