Jamie is a quality control specialist. He is required to check 180 rubber balls out of a shipment of 18,000for defects. He finds that 3 are defective. Of the balls in the bin, he predicts there will be 300 balls defective. What percent if the rubber balls are not defective?

18,000 - 180 = 17,820

17,820 / 18,000 = 0.99 = 99% are not defective
