>anyone who can tie their own shoes should know the opposing faces of a die always sum up to 7

I own dice that are not like this. They come in three kinds:
1. D3s have the same number on opposite faces.
2. Turn-taking dice are matched sets where no two dice can roll the same number. These count far beyond six.
3. Cheap dice from China are sometimes just made by people who don't know how normal dice are supposed to be.

A valid exercise can't assume such common things don't exist. Are you sure your shoes are tied?
