Question

How many ways are there to elect a president, vice-president, and a treasurer from a club of 8 students?

Answer 1

First the number of ways of selecting 3 students out of 8 is 8*7*6/(3*2*1)=56.
There are 6 ways of arranging the officers, so the total number of ways is 6*56=336

Answer 2

This would be 8C3   = 8*7*6 / (3*2*1)  =  56 answer
