There are several questions that arise: \n\u2013 How can we tell whether such a region is tileable in the first place?\n\u2013 If such a region is tileable, then how many tilings exist?\n\u2013 What does a \"typical\" tiling look like?\nIn this talk, we will introduce several theorems that answer these questions, and explore basic examples that illustrate these results.
