Question

Consider the following argument:

Answer 1

Answer:

$r \Rightarrow p\\ q \Rightarrow p\\ r \vee p\\ (r \vee q) \Rightarrow \neg r\\ s$

Step-by-step explanation:

$r \Rightarrow p \equiv (\neg r \vee p)$, p is false.

$q \Rightarrow p \equiv (\neg q \vee p)$, p is false.

$(r \vee q)$, r and q are falses.

$(r \vee q) \Rightarrow \neg r \equiv (\neg (r \vee q) \vee \neg r)$. this sentence is true.
