Think of a password 8 character long which uses at
last one lower-case letter, one capital letter, and one number, but
uses none more than once.
What's your password?
How many possible permutations are there for an 8 character password which meets those criteria?
How many fewer combinations without regard to order are there for an 8 character password which meets those requirements.
How would you calculate how many permutations there are for an 8 to 12 character password which meets those criteria?
