<h3>What is a contra positive statement?</h3>
A contrapositive statement is a proposition or theorem formed by contradicting both the subject and predicate or both the conclusion and hypothesis of a given proposition or theorem and interchanging them.
Example : "if not-B then not-A " is the contra positive of "if A then B "
Given the statement;
“if there is a lightning storm then we won’t go swimming”
The contra positive statement is;
"If we go swimming, then there is no lightning storm"
Thus, the contrapositive statement is "If we go swimming, then there is no lightning storm"
