1. Calculate the number of passwords that can be generated from the following character sets. Assume each password is 10 characters long. Use factorial or exponential notation to express your answer: · How many passwords can be generated from the set of 26 upper case alphabetic characters? You can use each character more then once (i.e. with replacement). · How many passwords can be generated from the set of upper and lower case alphabetic characters? You can use each character more then once (i.e. with replacement). 2.
