The total number of calculator units checked is 500, and 25 of them have non-functioning keys.

Relative frequency of non-defective calculators = (Total number of non-defective calculators) / (Total number of calculator units)

Total number of non-defective calculators = Total number of calculator units - Number of defective calculators
Total number of non-defective calculators = 500 - 25
Total number of non-defective calculators = 475

Relative frequency of non-defective calculators = 475 / 500
Relative frequency of non-defective calculators = 0.95

Therefore, the relative frequency of the non-defective calculators from the batch of 500 items is 0.95 or 95%.
