A system requires that all passwords contain only lower case letters and are between 6 and 8 letters long. Let x be a password on this system that contains exactly one word from the phrase "super strong password" as a substring. (a) What's the probability of guessing x on the first try? (b) If x is 8 characters long, and was encrypted as \vvfgdqqq" using an affine cipher, f(x) = (ax + b) mod 26, what was the key, (a; b)?
