Q. In a random sample of a particular model of drone,

2.5 \%

of the drones have a manufacturing defect. At this rate, how many of

,

000

Calculate Defective Drones: Calculate the number of defective drones by multiplying the total number of drones by the percentage of defects. $\newline$ $0.025 \times 4,000 = 100$
Find Correct Answer: Check the answer choices to find the correct one that matches the calculation. $\newline$ The correct answer is (C) $100$ .
