Let's take a look at your question. We have to pick 2 people from a 4 people group. And the order matter. We have 2 places: _____ _____. For the first place we have 4 options and for the second place, we have 3 options. So, there are 4*3=12 different ways to pick the 2 people. So, the correct answer is D. I hope this can help you. Feel free to ask me again if you have a doubt. Regards. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.

(A) 2 (B) 6 (C) 8 (D) 12 (E) 16 Since we have specific positions in the group, order matters, and so we have a permutation. Thus, the number of ways to select a steward and a treasurer from 4 employees is 4P2 = 4!/2! = 4 x 3 = 12 ways.

We're asked for the number of different ways that this can be accomplished. Starting with the shop steward, there are 4 options. Once once of those people is chosen... We then choose for the treasurer, so there will be 3 options. Total ways = (4)(3) = 12 Final Answer: D GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com • 5-Day Free Trial 5-day free, full-access trial TTP Quant Available with Beat the GMAT members only code • FREE GMAT Exam Know how you'd score today for$0
