<p>The post says that the offices are in order such that it goes x, not x, not x, x.</p>
<p>The poster on the bottom assumes (with the redoffice comparison) that the order can go x,x, not x, not x. </p>
<p>Doesn't this affect the problem?</p>
<p>No because this is a combination, order does not matter. We want both Karen and Tina to be in an x box so it doesn't make a difference if Karen or Tina is in the first or the second.</p>
<p>Oh, ok</p>
<p>Just to clarify, I know in combinations order doesn't matter, and in permutations it does, how to you check for that in a problem?</p>
<p>Permutations are for arrangements where order MATTERS, 4 people in a line question etc.</p>
<p>Combinations are for questions that deal with Committees, groups, teams, etc.</p>
<p>do you comprehend?</p>
<p>yes, comprendo</p>
