- first proposition $: \text{P} \Rightarrow \text{Q}$ second proposition $: \neg \text{P} \vee \text{Q}$
$\text{Answer}$: yes
$\text{Example reasoning}$:
All rows in the truth table evaluate to the same truth value.
$$\begin{array} {|c|c|c|c|} \hline \text{P} & \text{Q} & \text{P} \Rightarrow \text{Q} & \neg \text{P} \vee \text{Q} \\\hline \text{T} & \text{T} & \text{T} & \text{T} \\\hline \text{T} & \text{F} & \text{F} & \text{F} \\\hline \text{F} & \text{T} & \text{T} & \text{T} \\\hline \text{F} & \text{F} & \text{T} & \text{T} \\\hline \end{array}$$
- first proposition $: \neg \text{P}$ second proposition $: \text{P} \Rightarrow \text{False}$
$\text{Answer}:$ yes
