I’ll Calculator manufacturing company company check 500 calculator units in 25 of them. I have non-functioning case approximate the relative frequency of a non defective unit from the batch of items express your answer in the simplest form of a fraction
To calculate the relative frequency of a non-defective unit in the batch of items, we need to divide the number of non-defective units by the total number of units checked.
Since there are 500 calculator units in total and 25 of them were checked, the number of non-defective units can be calculated by subtracting the number of defective units from the total number of units checked. If all 25 units checked were non-defective, then the total number of non-defective units would be 25.
Therefore, the relative frequency of a non-defective unit in the batch of items is:
Non-defective units / Total units checked
= 25 / 500
= 1 / 20
Therefore, the relative frequency of a non-defective unit in the batch of items is 1/20.
