What is the converse of a statement?

A conditional statement with the antecedent and effect reversed is known as a converse statement.

It is given that:

The two conditional statements are p and q:

p is false

q is true

"p q" represents symbolically "If p then q," where p stands for the hypothesis and q for the conclusion.

If p is false and q is true then q p will be false.

Thus, the q p will be false if p is false and q is true after applying the conditional statement operation.
