Question

Which is a counterexample of the following conditional statement:

"If a number is divisible by 5, then it is an even number."
18
20
33
35

Answer 1

To determine a counterexample for the conditional statement "If a number is divisible by 5, then it is an even number," we need to find a number that is divisible by 5 and not even.

Let's analyze the options:

- **18**: This number is not divisible by 5.
- **20**: This number is divisible by 5 and is even.
- **33**: This number is not divisible by 5.
- **35**: This number is divisible by 5 but is odd (not even).

Since **35** is divisible by 5 and is not an even number, it serves as a counterexample to the given conditional statement.

Thus, the counterexample is **35**.
