A calculator manufacturing company checks 500 calculator units and 25 of them have non-functioning keys approximate the relative frequency of a non-defective unit from each Spotify items express your answer in the simplest form of a fraction
The relative frequency of non-defective units can be calculated as follows:
Number of non-defective units = Total units - Number of defective units
Number of non-defective units = 500 - 25 = 475
Relative frequency of non-defective units = Number of non-defective units / Total units
Relative frequency of non-defective units = 475 / 500
To simplify the fraction, we divide both numerator and denominator by 25:
Relative frequency of non-defective units = 19 / 20
So, the relative frequency of a non-defective unit from each 500 items is 19/20.
