Hint: Contrapositive means switching the hypothesis and conclusion of a conditional statement and negating both. The contrapositive of a conditional statement of the form "If p then q" is "If $ \sim q$ then $ \sim p$ ". Symbolically, the contrapositive of p q is $ \sim q \sim p$ .
Complete step-by-step answer:
Let us divide the statement into two parts P and Q .
P - If it is raining
Q - I will not come
i.e. P conditional to Q
We know that the contrapositive of $a \to b$ is $ \sim b \to \sim a$
Therefore the contrapositive of the statement becomes
If I come then it is not raining.
Note: Always remember that the contrapositive of a proposition or theorem formed by contradicting both the subject and predicate or both the hypothesis and conclusion of a given proposition or theorem and interchanging them "if not-B then not-A " is the contrapositive of "if A then B " .
