Solution
The contrapositive of p → q is ¬q → ¬p. This is a fundamental concept in logic and mathematics. Here's how it works:
-
Start with the original statement, p → q. This can be read as "if p then q."
-
The contrapositive of a statement is formed by negating both the hypothesis and the conclusion, and then reversing the direction of the implication.
-
So, for p → q, we first negate p and q to get ¬p and ¬q.
-
Then we reverse the direction of the implication to get ¬q → ¬p.
So, the contrapositive of p → q is ¬q → ¬p.
