Avery sets up a passcode on her smart phone, which allows only six-digit codes. She has heard that it's more secure if a digit is repeated in the passcode. A spy sneaks a look at Avery's smart phone and sees her fingerprints on the screen over five numbers. What is the probability the spy is able to unlock the smart phone on his first try? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
