when "If P, then Q" is true, "if not Q, then not P¨ is also true.
So the given statement is true.
Let's suppose we have a conditional statement:
If P, then Q.
That is true.
The statement says that:
If not Q, then not P.
Is also true.
Now, let's go to the original conditional statement.
"If P, then Q"
This means that always that P is true, then Q must also be true. But we can have cases where P is false and Q is true. (this means that Q can't be true if P is not true).
Now, if we affirm that Q is false (or not Q is true, these are the same thing). Then we must have that P is also false (or not P is true).
So the given statement is true.
when:
If P, then Q
is true.
if not Q, then not P¨
is also true.
