Question 423859: Vice Presidents The board of a pharmaceutical company has nine members. One board member will be selected as vice president of marketing, and a different board member will be selected as vice president of research. How many different arrangements of the two vice presidents are possible?
There are 9 ways to pick a vice president of marketing and 8 ways to pick the vice president of research
9!=9*8*7*6*5*4*3*2*1=362880 times for VP of marketing
8!= 8*7*6*5*4*3*2*1=40320 times for VP of research

total no. of ways to select two vice presidents = 9*8 = 72

so, answer is 72 only.
