Answer 1

The chance of finding a defective headset is 2.5%

How to determine the probability?

The given parameters are:

Total = 280

No defects = 273

The number of defective headsets is:

Defective = 280 - 273

Evaluate

Defective = 7

The probability that a defective headset is selected is:

P(Defective) = 7/280

Express as percentage

P(Defective) = 2.5%

Hence, the chance of finding a defective headset is 2.5%
