In a certain city of several million people, 6.4% of the adults are unemployed. If a random sample of 255 adults in this city is selected, approximate the probability that at most 17 in the sample are unemployed. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.
