In a batch of 1160 calculators, 5 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.

Respuesta :

To determine the probability that a calculator chosen at random is defective, divided the number found to be defective by the total number of calculators and multiply by 100%. In the given above, there are 5 defective calculators out of 1160. This is shown below, 
 
                                      (5 / 1160) x 100% = 0.43%

Thus, the answer is approximately 0.4%.

0.4
