A password for a computer system must consist of 6 distinct characters (note: "A" and "a" are considered distinct). For these characters, 4 can be letters that are lower or uppercase, and 2 must be digits. The letters and numbers can be placed in any order. How many distinct passwords are possible?
A password consists of 8 characters, the first two are identical vowels, the 6th character is '7', and the last character is an even digit less than 8. How many such passwords exist? (Repetition is allowed, characters are alphanumeric)
Passwords Suppose a password must have at least 8 characters, but no more than 12 characters, made up of letters (without distinction for case) and digits. If the password must contain at least one letter and at least one digit, how many passwords are possible?
