Assume that certain types of identification numbers range from 00-00-000 to 77-77-777, where only the digits 0 through 7 are used An identification number is randomly selected. a) What is the probability that the identification number contains 7 different numbers? b) What is the probability that the identification number contains at least one repeated digit? a) What is the total number of possible identification numbers? (Simplify your answer.) The probability that the identification number contains 7 different numbers is (Type an integer or decimal rounded to four decimal places as needed.). b) The probability that the identification number contains at least one repeated digit is (Type an integer or decimal rounded to four decimal places as needed.)
