In a batch of 890 calculators, 12 were found to be defective. What is the probability that a calculator chosen at random will be defective? Write the probability as a percent. Round to the nearest tenth of a percent if necessary
First, you'd have to write the probability as a fraction; which would be 12/890. Converting it to a percentage would bring you with 1.348314607%, or 1.34% when simplified
