Answer: 3% (3/100), 4% (1/25), and 5% (1/20)

Step-by-step explanation:

So, there are 100 recordable DVDs, and 5 are defective. The way you find the answer is by dividing 100 by 100, which equals one. That means you have a one percent chance to select one random DVD. But, since you need to find the probability of selecting at least three non-defective DVDs, you would need to multiply 1 by 3, 4 or 5 to get the percentages for you probability.
