Question

The probability of a potential employee passing a drug test is 91%. If you selected 15 potential employees and gave them a drug test, how many would you expect to pass the test

Answer 1

Answer:

The  number expected to pass that test is  $k = 14 \ employees$

Step-by-step explanation:

From the question we are told that

      The probability of  success is  p  =  0.91

       The sample size is  n  =  15  

 The number of employee that will pass the test is mathematically represented as

          $k = n * p$

substituting values

        $k = 15 * 0.91$

      $k = 14 \ employees$
