A manufacturing process produces semiconductor chips with a known failure rate of 7.8%. If a random sample of 290 chips is selected, approximate the probability that more than 20 will be defective. 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.
