A tent manufacturer knows from past data that there is an 13.1% chance of having a defect in the zipper of a tent and a 4.1% chance of having a defect in the seam sealing treatment on the tent. The machines that do these parts of the tent manufacturing are independent of each other, but every tent gets both a zipper and a seam sealing treatment. What is the probability that the tent will have neither a defective zipper nor a defective seam sealing treatment?
