Answer:
- 1) True
- 2) False
- 3) True
- 4) True
Step-by-step explanation:
This conditional statement:
- <em>If a its true, then b its true. </em>
Has a truth value of true if:
- both a and b are true.
- a its false, besides the truth value of b
And has a truth value of false, if
Then, for this statements:
<h3>1. p -> q</h3>
As both p and q are true, then, this statement is true.
<h3>2. p -> q</h3>
As p is true and q is false, this statement is false.
<h3>3. p->q</h3>
As p is false, this statement is true, no matter the truth value of q.
<h3>
4. ∼p -> q</h3>
∼p its the negation of p. if p is true, then ∼p is false. And this statement is true, no matter the truth value of q.
