## Answers ( No )

With one digit you can only make three numbers, 2, 5, and 8.

With two digits, _ _ there are 3 possibilities for the first digit and 2 in the second totaling 3*2 = 6 possibilities.

With three digits, _ _ _, there are 3 possibles in the first digit, 2 in the second and only 1 in the last. 3*2*1 = 6

Now we add all of the possibilities – 3+6+6 = 15.

Your final answer should be 15 numbers. Hope this helps!
