Determine whether the following statement is a tautology, contradiction, or neither (~PVQ) ~Q Tautology Contradiction • Neither
Tom [10]

Answer:

The statement (\lnot P \lor Q)\rightarrow \lnot Q is neither a tautology nor a contradiction.

Step-by-step explanation:

A tautology is a statement that is always true.

A contradiction is a statement that is always false.

We are going to use a truth table to determine whether the statement (\lnot P \lor Q)\rightarrow \lnot Q is a tautology, contradiction, or neither

A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.

The statement (\lnot P \lor Q)\rightarrow \lnot Q is compound by these simple statements:

  • \lnot P
  • \lnot Q
  • (\lnot P \lor Q)

and we are going to use these simple statements to build the truth table.

The last column contains true and false values. Therefore, the statement is neither a tautology nor a contradiction.
