Kiara sets up a passcode on her tablet, 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 Kiara's tablet and sees her fingerprints on the screen over five numbers. What is the probability the spy is able to unlock the tablet on his first try? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
