I wasted a lot of time (as, apparently, at least one other poster) thinking we were drawing pairs of cards. The problem statement could be clarified that we are drawing one card at a time and checking if this card forms a pair with the previous card.

Yes, I made the same mistake. What I found confusing was the phrase "consecutive pair." It's true it doesn't say consecutive pairs, but actually I thought that must be the interpretation since just finding the first pair was too easy! On the plus side, solving the problem assuming two consecutive pairs had to be drawn was more interesting.

Sorry for the confusion. We have changed the wording to make it clear that it is only ONE pair that we are looking for.

Thanks for the change. It should be clear now.
