The number of clocks that are not defective is an illustration of proportions
Of the 10000 clocks, 9250 are probably not defective
<h3>How to determine the number of clocks that are not defective?</h3>
From the complete question, we have the following parameter:
15 out of 200 clocks are defective
The above means that the number of clocks that are not defective is:
Not defective = 200 - 15
Not defective = 185
Express as percentage
Not defective = 185/200
Not defective = 92.5%
In 10,000 the number of clocks that are not defective would be:
Not defective = 92.5% * 10000
Not defective = 9250
Hence, 9250 of the 10000 clocks are probably not defective
