To find the relative frequency of a non-defective calculator from this batch, we first need to calculate the total number of non-defective calculators in the batch.
Total calculators checked = 500
Number of defective calculators = 25
Number of non-defective calculators = Total calculators checked - Number of defective calculators
= 500 - 25
= 475
Relative frequency of a non-defective calculator = Number of non-defective calculators / Total calculators checked
= 475 / 500
= 0.95
Therefore, the relative frequency of a non-defective calculator from this batch is 0.95 or 95%.
The calculator manufacturing company checks 500 calculators in the finds that 25 of them have non-functioning keys what is the relative frequency of a non-deffective calculator from this batch

Can you do it in fraction form
Sure!
Relative frequency of a non-defective calculator = Number of non-defective calculators / Total calculators checked
= 475 / 500
To simplify the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 25.
475 ÷ 25 = 19
500 ÷ 25 = 20
Therefore, the relative frequency of a non-defective calculator in fraction form is 19/20.
