I know I should know this... possible combinations?
My brain keeps telling me I should know how to do this, but I'm drawing a blank...
Looking at serial numbers all day. The first 6 number/letters never change, only the last three change. Either 0-9 or A-Z, and any combination of. xxxxxx09c, xxxxxx7u2, xxxxxx981, xxxxxx5tg, etc.
So how many possible combinations does that allow? More importantly, how is it figured? My brain wants to know.
