A proper analysis requires an acceptable defect rate, how willing you are to miss a worse defect rate, and how willing you are to get false positives. I can probably dig up an online sample size calculator if you're interested.
But if you want something simple you can convey, if the defect rate was as high as 15%(!), the odds of finding a defect after three checks is a meager: 1 - 0.85*0.85*0.85 = 39%
