Answer 1

Tautology ok mark it brainly

Answer 2

Two statement patterns A and B are said to be logically equivalent if A ↔ B is a Tautology or a contradiction.

• The compound proposition biconditional (denoted by A↔B) is true only when A and B have the same truth values, otherwise, it is false.
• A compound proposition that is always false for all possible combinations of the truth values of its components is called a contradiction.
• A compound proposition that is always true for all possible combinations of the truth values of its components is called a Tautology.
• The distinction of any two propositions is false if the disjuncts are both false otherwise it's true.
• Contingency is when a possible event cannot be predicted with certainty.
