Document Summary
A premise a implies a proposition b, written. If either of these conditions is true: aba. Conjunction tells what they tell jointly a b bba. We generalize the boolean logic of implication among assertions to that of relative degree represented by real numbers where a symbolizes a real number, indicating the degree to which premise a implies proposition b b. Zyxff dcb cba ba a b a c y z. Derivation of probability alt a dc bab bafb dcb dc b af af. We could have grouped the assertions differently a. As a particular solution we can take which gives cb a a bab c yxf. Xy and can be written in a more familiar form by changing notation acb bacab. The degree to which a premise implies an assertion determines the degree to which the premise implies its contradictory. a.
