# Combinatorics: Creating a password with characters, numbers, and one special character

I have a question that goes as follows

A password must consist of $$16$$ characters. Each character can be a digit ($$0 − 9$$), an uppercase or lowercase letter ($$A-Z$$, $$a-z$$) or one out of ten special characters. How many valid passwords are there?

I think it would be $$P(62,15) + P(10,1)$$, but I'm not entirely sure.
