I was recently given two solid copper dice in exchange for volunteering to roll each of them one thousand times, and report the results. Shire Post Mint are hand-making the dice, and have been receiving some questions from purchasers about their fairness. They weren’t sure what the standard methodology is for testing the reliability of random rolls. (It’s called a Chi-squared test.) So, I just finished rolling the dice (and providing analysis of the results for free).
