Best ResponseYou've already chosen the best response.0This is a combination/permutation problem. Since "order" does matter, ie, if Sally, Bob and Mike are the three officers, there can be multiple ways to fill the positions: Sally could be Pres, Bob Sec, and Mike Treas, or Sally could be Sec, Bob Pres, Mike Treas, and so on. Thus, this is a permutation. If order did not matter, ie, all three held the same title, then it would be a combination. A permutation can be written as nPr where n=total group, P means permutation, and r=number chosen. Thus, this would be 20P3.

Best ResponseYou've already chosen the best response.0Permutation is calculated as n!/(nr)! For #1, this is 20!/(203)! = 20*19*18. For #2, it is 8!/(85)!. This equals 8*7*6*5*4*3*2*1/(3*2*1) which equals 8*7*6*5*4. See why? So A is not correct...
