Review the truth table for conditional statements.
True. Since the conclusion is false, the converse of the statement must be true. The converse and inverse are logically equivalent, so the inverse is also true.
Practice makes perfect
Let's begin by reviewing the concept of a conditional and its inverse.
Conditional
Inverse
p→q
∼p→∼q
We know that the hypothesis p is true, and the conclusion q is false.
true→false
To form the inverse, we negate both the hypothesis and the conclusion of the conditional. The negation of true is false, and the negation of false is true.
Inverse∼true→∼false⇔false→true
Recall that when a hypothesis is false, the conditional will always be considered true, regardless of whether the conclusion is true or false. In this case, the hypothesis of the inverse is false, so we can conclude that the inverse of our statement is true.
