Question

An inspector checks 98 cell phones and finds that 2 of them are defective. A company has 850 of these phones. How many of the company's phones are likely to be defective?

Answer 1

17

Explanation:

As 2 phones are defective from a group of 98 that were checked, you can determine a percentage:

2/98= 2%

This indicates that 2% of the phones are likely to be defective and because of that you can find 2% of 850:

850*2%= 17

According to this, 17 phones are likely to be defective.
