Presets
Roll one die and every outcome is equally likely — a flat distribution. Roll several and sum them, and the shape becomes a bell: middle sums have many combinations, extremes have few. This is the central limit theorem in miniature, and why 7 is the most common roll of two dice and the heart of the game of craps.

Reading this result: Your target sits right at the peak: sums near the mean of 7 have the most combinations while the extremes have just one each — the central limit theorem in miniature.
