Are access codes like OOO00 allowed? Three letters "O" followed by two zeros "0"?

If so:

Choose the 1st character, a letter, 26 ways. Then:
Choose the 2nd character, a letter, 26 ways.
Choose the 3rd character, a digit, 10 ways.
Choose the 4th character, a digit, 10 ways.
Choose the 5th character, a digit, 10 ways. 

That's (26)(26)(10)(10)(10) = 676000 different access codes.

--------------
26*26*26*10*10
---
If "A" is different from "a" then 52*52*52*10*10
If A and a are different, it's called "case sensitive," upper case and lower case are separate.

Thx for explaining what digits are.
