Logically equivalent, logical equivalence, английский
Two propositions are logically equivalent if they always have the same truth value. that is, the propositions p and q are logically equivalent if p is true whenever q is true and p is false whenever q is false. the proposition (p ↔ q) is always true if and only if p and q are logically equivalent. for example, p is logically equivalent to p, to (p & p), and to (p | p); (p | (!p)) is logically equivalent to true; (p & !p) is logically equivalent to false; (p ↔ p) is logically equivalent to true; and (p → q) is logically equivalent to (!p | q).
Disjoint or mutually exclusive events, английский
Two events are disjoint or mutually exclusive if the occurrence of one is incompatible with the occurrence of the other; that is, if they can`t both happen at once (if they have no outcome in common). equivalently, two events are disjoint if their intersection is the empty set.
