- A counterexample is an example that disproves a statement1234. Here are some examples of counterexamples:
- The statement “all dogs are hairy” can be proved false by finding just one hairless dog2.
- The statement “all prime numbers are odd” is false because the counterexample of 2 shows that there is at least one even prime number4.
- The statement “all quadratic equations have two distinct roots” is false because the counterexample of x^2 = 0 shows that some quadratic equations can have only one root4.
- The statement “If a food is a fruit, then it is an apple” is false because mango is a fruit, but it is not an apple1.

Example: the statement “all dogs are hairy” can be proved false by finding just one hairless dog (the counterexample) like below.heimduo.org/what-is-an-example-of-a-counterexam…To give a counterexample, I have to find an integer n such n2 is divisible by 4, but n is not divisible by 4 — the “if” part must be true, but the “then” part must be false. Consider n = 6. Then n2 = 36 is divisible by 4, but n = 6 is not divisible by 4. Thus, n = 6 is a counterexample to the statement. On the other hand, consider n = 5.sites.millersville.edu/bikenaga/math-proof/countere…Examples of Counterexamples in Mathematics:
- Prime numbers: The statement “all prime numbers are odd” is false because the counterexample of 2 shows that there is at least one even prime number. Therefore, 2 is a counterexample to the statement.

A counterexample is any exception to a generalization. In logic a counterexample disproves the generalization, and does so rigorously in the fields of mathematics and philosophy. For example, the fact that "student John Smith is not lazy" is a counterexample to the generalization "students are lazy", and both a counterexample to, and disproof of, the universal quantification "all students are lazy."
