A study suggests that 16.5% 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 six people are
selected at random, what is the probability that at least one of them will have repeating digits?

The answer is

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
