if a club has 18 memebers how many different arragments of president, vice president, and secreary are possible
18! ----- right? 15! 3!
Start by selecting a president, then a vice president from the remaining persons and the secretary at last. Observe that for any choice of a president there are the same number of choices for a vice president etc.
no it was suppose to be a number right answer was 4896
amistre64 your answer takes the formula for selecting 3 out of 18 without taking different orders into account. But here it is important who of the three is president, vice president and secretary and in your model that can only be determined by the order.
....still get those confused :) 18! --- = 4896 tho :) 15!
18 possibles for the first one; 17 possibles for the 2nd, and 16 possibles for the 3rd..= 4896
indeed :-)
