Atest subject is randomly selected for a diabetes test. what is the probability of getting a subject who is not diabetic, given that the test result is negative? find the probability using the data table.
see attachment below for answer choices/table.

From the image we obtain the following values, 

                                         Positive Test           Negative Test
Subject is diabetic             35                                  3                      38
Subject is not diabetic        5                                28                       33
Total                                      40                               31                       71

Therefore, the probability of getting a subject that is not diabetic is calculated as follows:

28/31 = 0.903 or 90.3%

The answer is 90.3%.
