confusing math problem please help me!! ive been stuck all night..?

Question

Which is a counterexample of the following conditional:
“If a number is divisible by three, then it is odd.”

1

3

6

9

Answer 1

The proposition is wrong.

It is not necessary that a number divisible by 3 must be odd.

There are so many even numbers which are divisible by 3.

6,12,18,24,30,36,42,48............

In fact starting from three, every alternate number divisible by 3 is even.

Answer 2

A counterexample will satisfy the "if" part, but not the "then" part.

1 is not a counterexample because it isn't divisible by 3 (doesn't satisfy the "if" part).

3 satisfies both the "if" and "then" parts, so it's not a counterexample.

I'll let you check the last two proposed counterexamples.

Answer 3

ya its 6
cuz 9 divided by 3 is 3
3 div by 3 is 1
and 1 div by 3 is 1/3(odd)

Answer 4

6 is not odd
