A computer system uses passwords that contain exactly 5 characters, and each character is one of the 26 lowercase letters (a–z) or 26 uppercase letters (A–Z) or 10 integers (0–9). Let ? 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. Suppose that all passwords in ? are equally likely. Determine the following probabilities. a. P(A|B′) = b. P(A′ ∩ B′) = c. The probability that password contains exactly 2 integers given that it contains at least 1 integer. P =
