<logic> A notion introduced by Florentin Smarandache: The
probability (T, I, F) that an event occurs is calculated from
different sources which may be contradictory or may overlap
information; here T, I, F are real subsets representing the
truth, indeterminacy, and falsity percentages respectively,
and n_sup = sup(T)+sup(I)+sup(F) > 100.
