Start Fraction 475 over 500 End Fraction
The relative frequency of a non-defective unit can be calculated by subtracting the frequency of defective units from the total number of units, and then dividing by the total number of units.
Relative frequency = (500 - 25) / 500
Relative frequency = 475 / 500
Relative frequency = Start Fraction 475 over 500 End Fraction
Therefore, the relative frequency of a non-defective unit is Start Fraction 475 over 500 End Fraction.
