WebInclusive and exclusive disjunction [ edit] Because the logical "or" means a formula is when either or both are true, it is referred to as an inclusive disjunction. This is in contrast with an exclusive disjunction, which is true when one or the other of the arguments are true, but not both (referred to as " exclusive or ", or "XOR").
