1. An optometry clinic's office is instituting a new system for patient identification numbers. Under the new system, each username must be exactly 6 characters long; available characters are either uppercase or lowercase letters (A-Z or a-z, 52 possible choices) and numerical digits (0-9, 10 possible choices). The clinic's office would like the first character being uppercase letter, the last three characters to be numerical digits, and the middle two characters to be lowercase letter. (a) How many different ID are possible (assume letters and numbers can be chosen more than once)? (b) How many different ID are possible if none of the numerical digits can be used more than once? (c) How many different ID are possible if no character (letters or numbers) can be used more than once?
