(An elementary proposition is a truth-function of itself.)
That is the foundation of the theory of probability.
The truth-operation is the way in which a truth-function arises from elementary propositions.
According to the nature of truth-operations, in the same way as out of elementary propositions arise their truth-functions, from truth-functions arises a new one. Every truth-operation creates from truth-functions of elementary propositions, another tru th-function of elementary propositions i.e. a proposition. The result of every truth-operation on the reults of truth-operations on elementary propositions is also the result of one truth-operation on elementary propositions.
Every proposition is the result of truth-operations on elementary propositions.
This operation denies all the propositions in the right-hand bracket and I call it the negation of these propositions.
