The statement is true by using indirect reasoning.

Explanation of Solution
Given information:
James, Hector, and Mandy all have different colour cars. Only one of the statement below is true. Use indirect reasoning to determine which statement is true. Explain.
Calculation:
In an indirect proof or proof by contradiction, assume that the conclusion is false. By showing the assumption to be logically impossible, prove the assumption is false and the original conclusion is true. For this problem, assume that each statement is not true and look for a contradiction to your assumption.
Let assume that if statement
Else the statement
