A four-character password to log onto a computer is drawn from the digits 0-9 and a subset of 22 letters of the alphabet (repetition is permitted). Determine the number of passwords possible if a) the letters used are not case sensitive (that is, a lowercase letter is treated the same as an uppercase letter). b) the letters used are case sensitive (that is, an uppercase letter is considered different than the same lowercase letter). a) There are possible passwords if the letters used are not case sensitive. (Type a whole number.) Enter your answer in the answer box and then click Check Answer.
