password has to be exactly 8 characters long.
Must use: upper case letters- A, B, C,D...Z and lower case letters-
a, b,c, d ..., z and digits- 0, 1,2, ..., 9
If A is the set of passwords with NO upper case letter and B is
the set of passwords with NO lower case letter, then what is the
size of |A ∪ B|?

A password is required to be 12 to 16 characters in length. Characters can be digits (0-9), upper or lower-case letters (A-Z, a-z) or special characters. There are 10 permitted special characters. There is an additional rule that not all characters can be letters (i.e. there has to be at least one digit or one special character) ow many permitted passwords are there?

A computer system uses passwords that contain exactly 4 characters, and each character is 1 of the 3 lowercase letters (a, b, c) or 3 upper case letters (A, B, C) or the 5 odd digits (1, 3, 5, 7, 9). Let Ω denote the set of all possible passwords, and let A and B denote the events that consist of passwords with only letters or only integers, respectively. Determine the probability that a password contains only numbers given that...
