Extra 5 / 12 · Uncertainty
Shared and separate uncertainty
Two quantities are each described as “about one cup.” The description alone does not say they have the same volume. Subtracting one quantity from itself is a different operation.

What is checked, and where this example stops
Closed affine support reads yield [90,110], [0,0] and [−20,20] in hundredths of a cup. Shared quantity and bias cancel between two events, leaving [−2,2] event noise.
These are bounds conditional on the stated premises, not normal distributions or probability estimates. Distinct slots do not prove statistical independence.
