| Question 2 |
If the proposition ¬ P → Q is true, then the truth value of the proportion ¬ PV (P → Q) is:
| True | |
| Multi – Valued | |
| Flase | |
| Can not determined |
Question 2 Explanation:
We can also write (¬p → q) into (p ∨ q)
Here, we can minimize the boolean form into
¬p ∨ (p → q)
= ¬p ∨ (¬p ∨ q)
= ¬p ∨ q
In question, they are not discussed about the truth values of p, it implies that ¬p ∨ q also be True or False. So, we cannot be determined.

¬p ∨ (p → q)
= ¬p ∨ (¬p ∨ q)
= ¬p ∨ q
In question, they are not discussed about the truth values of p, it implies that ¬p ∨ q also be True or False. So, we cannot be determined.
