The idea
When a thing can happen in several ways that cannot happen together, its chance is the sum across those ways.
In practice
The bakery's last loaf is rye 0.5, wheat 0.3, seeded 0.2 — rye or wheat: 0.8.
Where people slip
Adding is licensed by exclusivity — one loaf cannot be two breads; overlapping ways need subtler books.
