Question
$p\ v\ (p \rightarrow\ \sim p)$

Answer

Truth table:
  $1$ $2$ $3$ $4$
$p$ $\sim p$ $p \rightarrow\ \sim q$ $p\ v\ (p \rightarrow\  \sim p)$
$1$ $T$ $F$ $F$ $T$
$2$ $F$ $T$ $T$ $T$
  $1(\sim )$ $1, 2 ( \rightarrow )$ $1, 3(v)$
Decision of the type of form for the statement: Looking at the fact sheet above, it will be seen that the representation of the given form for the statement is in column no. $4.$ All rows in this column have a $'T'.$ This means that all substitutions for this form of statement are true. So it is clear that this form of statement is 'meaningful'.
