Explanation:

Step1: Find the non - defect rate

The defect rate is 2%, so the non - defect rate is $100\% - 2\%=98\%$ or in decimal form, $0.98$.

Step2: Calculate the number of non - defective parts

We know the total number of parts is 150. To find the number of non - defective parts, we multiply the total number of parts by the non - defect rate. So the number of non - defective parts $=150\times0.98 = 147$.

Answer:

147
