Hello team,

I think below problem in the variation quiz has wrong answer.

Going back to the combination lock example from the lecture, imagine the correct code consisted of a single 4-letter word. However, this time the passcode only consists of the letters of “password”. How many possible passcodes are there?

4^8

incorrect8^4
7^4

4^7

I think Correct option is 8^4. The word 'Password' contains eight letters and correct code consisted of single 4-letters. thus it may be 8^4.

Correct me if I am wrong.
