17

Step-by-step 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.
