A three-digit personal identification number is chosen using the digits 1–9. The digits cannot be repeated.What is the approximate probability that the first digit will be 6?

Each of the digits 1 through 9 is equally likely to be the first digit. The probability that the first digit is 6 is therefore 1 out of 9, or approximately 0.11111. The fact that digits cannot repeat does not change the probability for the first digit.
