ДИЗЪЮНКЦИЯ
Disjunction
A logical operation forming a compound sentence by combining two sentences by means of the logical sentential connective "or". Symbolically, it is A∨B (read A or B). Classical mathematical logic differentiates between two types of Disjunction: the inclusive (conjunctive) and exclusive (disjunctive). An inclusive Disjunction forms a complex sentence, judgement or proposition which is true if at least one of its predicates is true, and false if all its component predicates are false. In common speech it coincides with the non-disjunctive meaning of the connective "or". Exclusive Disjunction forms a compound statement, judgement or proposition which is true only if one of its members is true. In common speech it coincides with the disjunctive meaning of the connective "or" (in the sense of "either... or").
