Stats help?

 The technology company DataGenetics suggests that 17.8 % of all four-digit personal identification numbers, or PIN codes, have a repeating digits format such as 2525 . Assuming this to be true, if the PIN codes of nine people are selected at random, what is the probability that at least one of them will have repeating digits? Round your answer to four decimal places.

    Based on what you are saying, there would be 100 occurrences of what you call repeating digits (0000, 0101, 0202, ... , 9898, 9999).  I'm too lazy to do the rest.  See if somebody else can help you.
