How many 8-digit telephone numbers have one or more repeated digits?

Well, that depends on what rules you want to follow as far as formatting the number is concerned. Can the first digit be a zero? Can it be anything other than a 1?. That is, does it have to be a valid phone number? Let's assume that the first digit can be anything. We can work the answer out as follows: Total number of 8-digit numbers (with preceding 0's): 108 Total number of 8-digit numbers that have all unique digits: 10! / 2! Therefore, the total number of 8-digit numbers - allowing preceding 0's - would be 108 - 10!/2! = 100000000 - 1814400 = 98185600 Now, if you don't want to allow a preceding zero, then your first digit can only be 1-9. So instead we get: 9 * 107 - 9 * (9! / 2!) = 90000000 - 1632960 = 88367040
