this question is confusing i dont understand it
Hello, sabina_19!
It seems clear enough . . . What part is confusing?
By using the appropriate truth tables, decide whethr
each of the following is tautology, absurdity, or contingency.
A tautology is always true.
An absurdity is always false.
A contingency is sometime true, sometimes false. .("It depends.")
$\displaystyle (a)\;\;\begin{array}{|c||ccc|}\hline
p & p & \to & p \\ \hline \hline
T & T & {\color{blue}T} & T \\ \hline
F & F & {\color{blue}T} & F \\ \hline \end{array}\qquad \text{Tautology}$
$\displaystyle (b)\;\;\begin{array}{|c||ccc|}\hline
p & p & \to & \sim\!p \\ \hline \hline
T & T & {\color{blue}F} & F \\ F & F &{\color{blue}T} & T \\ \hline
\end{array}\qquad\text{Contingency}$
$\displaystyle (c)\;\;\begin{array}{|c||ccc|} \hline
p & p & \wedge & \sim\!p \\ \hline \hline
T & T& {\color{blue}F} & F \\ \hline
F & F & {\color{blue}F} & T \\ \hline \end{array}\qquad\text{Absurdity}$
