Ms. Sue, wouldn't it be 9^10? I think 0 wasn't included, so it would be 10 numbers not 9.....right???
I'm not sure.
Please post this as a New Question. That way a math tutor may be able to help you.
For social security numbers, 0 can be included.
n^r = 10^9, where n is the number of things to choose from, and you choose r of them (Repetition allowed, order matters)
so it would be 1,000,000,000???
