  The way I did it, and I thought he would too, was by considering the possible placements of B for any place of A. Since after we have defined 2 of the 4 elements, the other two can only be arranged in two ways. Then, you can add up all the ways to put A before B with considering the other two elements as one singular one, and then multiply by 2.
  So, with A in front 3 placements work, second, 2 and so on, so that we get 3+2+1=6. Then, we multiply by 2 to get 12.
  this also works on the your turn, except that there is actually only 1 arrangement of C and D for every placement of b.

  "The only ways we want are those in the first category, which equals 1/2 of the total ways."
  Is this a typo, because the answer should be 1/4 of the total ways(as stated before in the explanation), and the first category only takes up 1/4 of all the categories?
