A hacker is trying to guess someone's password. The hacker knows (somehow) that the password is14 characters long, and that each character is either a lowercase letter, (a, b, c, etc.), an uppercaseletter (A, B, C, etc.) or a numerical digit (0, 1, 2, 3, 4, 5, 6, 7, 8, or 9). Assume that the hacker makesrandom guesses.What is the probability that the hacker guesses the password on his first try? Enter your answer as adecimal or a fraction, not a percentage.
