1) An easy way to increase password security is to require that each password have at least a certain minimum length. This certainly helps increase the number of possibilities. a) Assuming that the password is NOT case-sensitive and that letters can be used more than once, how many 6 letter passwords are possible? b) Investigate how this changes as the minimum length is increased by finding the number of possible 8 and 10 letter passwords under the same assumptions.
