Question
Determine the validity of the following arguments using the direct method of truth table
$P\ v\ Q$
$\sim P$
$\therefore Q$

Answer

Combining the two bases of this argument as a whole, the argument will be as follows:
$(P\ v\ Q)\ \&\ \sim\ P$
$\therefore Q$
Truth Table:
  Support Statement The resulting statement
  $1$ $2$ $3$ $4$ $5$ $6$
$P$ $Q$ $\sim P$ $P\ v\ Q$ $(P\ v\ Q)\ \&\ \sim P$ $Q$
$1$ $T$ $T$ $F$ $T$ $F$ $T$
$2$ $T$ $F$ $F$ $T$ $F$ $F$
$3$ $F$ $T$ $T$ $T$ $T^*$ $T^*$
$4$ $F$ $F$ $T$ $F$ F $F$
  $1 (\sim )$ $1, 2(v)$ $4, 3(\&)$ As $2$
               
Judgment of the validity of the argument: A total of six columns are presented in the above fact sheet. In which the column no. Base statement and column no.$ 6$ is the representation of the result statement. Row out of the total four rows of the truth table. The base statement in $3$ is the truth $‘T’$ and the resulting statement in the same row is also the truth $‘T’.$ Hence this argument is standard.
