Permutation/ Combination Stats Question Watch
If 3 candidates are to be chosen from a pool of 5 potential candidates to form a committee, how many different committees are possible? If these 3 candidates are to be made president, vice- president and secretary, how many different such committees are possible?
Are there two parts to this question (as in first part is a combination and second part a permutation)? Or can the whole question be answered by calculating just one or the other? Thanks.

In parentheses - That is one way to look at it.
Since in the first committee you're just choosing 3 people and each post is the same as any other (though that's not explicitely stated), whereas in the second you are allocating the 3 people to specific posts in the committee, then you'd expect a different number of possibilities.
