A domino is a rectangular tile composed of two squares. Each square may contain an integer from 0 to 12, and each integer within this range is paired with every other integer exactly once to form a complete domino set. A $\textit{double}$ is a domino that has the same integer on both of its squares. What is the probability that a domino randomly selected from the set will be a $\textit{double}$?
