Question

what is tatology and its 2 examples ​

Answer 1

Answer:

A tautology is any logical sentence that is always true. This means that no matter the truth value of each boolean variable, the sentence still remains true.

Two basic examples:

    $A\lor\neg A$

    This must be true as A must either be true or false.

    $(P\land Q) \to P$

    If P and Q are true then P must be true.
