To find the number of drones that have a manufacturing defect, we can calculate 2.5% of 4,000.
First, convert the percentage to a decimal:
\[
2.5\% = \frac{2.5}{100} = 0.025
\]
Next, multiply this decimal by the total number of drones:
\[
\text{Number of defective drones} = 0.025 \times 4000
\]
Calculating that gives:
\[
\text{Number of defective drones} = 100
\]
Therefore, out of 4,000 drones, approximately **100 drones** will have a manufacturing defect.
