Question

Establish the validity of the following argument: $\neg q \lor (r \land s)$ $p \to q$ $r \to (\neg t \lor u)$ $\neg t \lor p$ $\therefore t \to u$

          Establish the validity of the following argument:
$\neg q \lor (r \land s)$
$p \to q$
$r \to (\neg t \lor u)$
$\neg t \lor p$
$\therefore t \to u$

q (r s)
p → q
r → ( t u)
t p
∴ t → u
