How this data is usedHelp
All coins look alike. Exactly one has a different weight. Put equal numbers on the two pans, observe the result and use your recorded evidence to identify the coin. A conclusion is accepted only when no other explanation fits. You may keep weighing beyond the target. Viewing possibilities or a suggested weighing counts as help.
