How many 5 character passwords are possible if the same character can be repeated all 5 times?
3125 possible passwords
We can’t use the permutation problem to solve this problem, so we will use the Fundamental Counting Principle. In order to form a password, we need to make five decisions. (5) times (5) times (5) times (5) times (5) = 3125. There are 3125 possible passwords, if a password may have repeated characters.

10,000 possible combinations
Berry analyzed passwords from previously released and exposed tables and security breaches, filtering the results to just those that were exactly four digits long [0-9]. There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code.
What is the number of passwords with 1 letter and 3 digits?
Thanks to the comment I received from Mr Alan Klette, I realized that I had not paid sufficient attention to the wording of the question. The correct answers are: Passwords with 1 letter and 3 digits: 26 (letters of the alphabet of the english language)*10^3 (three integers, each 0 to 9)=26000.
How many six-character passwords are there?
The easiest way to count the acceptable passwords is to note that there are 36 6 six-character strings made up of upper-case letters and digits, and 26 6 of them are made up entirely of letters, so there are 36 6 − 26 6 that include at least one digit. It is possible to count them directly, but the counting is more complicated.
How many numbers are there in 26000 passwords?
The correct answers are: Passwords with 1 letter and 3 digits: 26 (letters of the alphabet of the english language)*10^3 (three integers, each 0 to 9)=26000. Passwords with 1 letter and 4 digits:26* (10^4)=260000. Passwords with 3 or 4 digits: 26000 + 260000=286000.
What is the maximum possible permutations of Part Two of the password?
We have ten digits to choose from, and four places in which to put them. 10^4 is 10,000, but you can’t quite get there – you can only get to 9,999. This means that the maximum possible permutations of part two of the password is 9,999.
