In a tire factor, the quality control inspector examines a randomly chosen sample of 16 tires. When more than one defective tire is found, production is halted, the existing tires are recycled, and production is then resumed. The purpose of this process is to ensure the defect rate is no more than 6%. Occasionally, by bad luck, even if the defect rate is no more than 6%, more than one defective tire is found from the chosen 16. What percent of the time does this happen? Assume defect rate is equal to 6%
