The idea
The chances of all the ways one situation can resolve always sum to exactly 1 — the whole drum, accounted for.
In practice
Your 250 raffle tickets give 0.25; everyone else's give 0.75; together, 1.
Where people slip
Books that sum past 1 or short of it mean a case was invented or lost — audit before trusting.
