You will have 120 possibles (combinations) of passwords with 2 digits and 3 letters.
5! = 5 x 4 x 3 x 2 x 1 = 120

How many license plates can be made using either two uppercase English letters followed by four digits or two digits followed by four uppercase English letters?
35,152,000 (assuming that 000 is a valid number, and that no letter combinations are disallowed for offensive connotations.) Also, no letters are disallowed because of possible confusion between letters and numbers eg 0 and O.
it 26 to the power 4 and then 99 for the numbers figure that out add the two together
How many digits in a fed referemce number?
You can make 916,132,832 different five-character passwords if the code can be a mixture of letters and digits in any order and is case sensitive.
3!*3!=36For example, if you want to use the alphabets a,b,c and three digits 1,2,3 you can make the following 36 different passwords (3 letters followed by 3 digits)abc123abc132abc231abc213abc312abc321acb123acb132acb231acb213acb312acb321bca123bca132bca231bca213bca312bca321bac123bac132bac231bac213bac312bac321cab123cab132cab231cab213cab312cab321cba123cba132cab231cab213cab312cab321

The number of 4 digit codes, using different digits, is 10*9*8*7 = 5040. However, computer passwords can, usually, have repeated digits and, if that is allowed, you can have 104 = 10000 codes.
Assuming repeats are allowed and case (of the letters) is ignored then there are: 26^2 × 10^4 = 6,760,000
3 letters
676,000 possibilities. For case-sensitive passwords, it's 2,704,000 possibilities. Passwords consist of 2 letters and 3 digits. That's 5 places. The first and second places can each hold 1 of 26 possibilities (26 letters), and positions 3, 4, and 5 can each hold 1 of 10 possibilities. The answer is 26 x 26 x 10 x 10 x 10 = 676000. Maybe the passwords can be case-sensitive (i.e. an upper case letter is different from a lower-case letter), then there will be 52 possibilities for each letter - in each of the 1st and 2nd places. This gives the total as 52 * 52 * 10 * 10 * 10 = 2,704,000. Note: An assumption we made is that the passwords are only 5 characters, consisting of 2 letters and 3 digits only. The question didn't say that no other characters are between these letters and numbers. If there are, then we don't have enough info to answer the question.
How many license plates can be made using either two uppercase English letters followed by four digits or two digits followed by four uppercase English letters?

Assuming a 3-digit password can begin with a zero, the answer is 720.
I do not have a pasward. On the other hand, I have many passwords. I believe that is what you mean. Your password is your secret key to get into a computer account, bank account, or any type of account. Passwords can be made from any combination of lowercase letters, uppercase letters, numbers, and symbols. If you are asking what specific passwords people reading this use, that is rude. Hopefully no one will be stupid enough to tell you what their passwords are.
