Anyone please help ASAP!! A hiking club has 9 members. How many ways can they choose a president, vice president, secretary, and treasurer from among the members? A. 3024 B. 36 C. 6561 D. 126

jimthompson5910 (jim_thompson5910):

you have 9 people, so you have 9 choices for president after choosing that 1 person for president, you now have 8 choices for VP then after that, you have 7 choices for secretary and finally, you'll have 6 choices for treasurer

jimthompson5910 (jim_thompson5910):

multiply out those choices to get your answer

no that's not right.. ughh

jimthompson5910 (jim_thompson5910):

you don't keep going, you stop at 6 because you're not picking all 9 people

jimthompson5910 (jim_thompson5910):

you'll be computing 9*8*7*6

Oh I see so the answer would be 3024

jimthompson5910 (jim_thompson5910):
