Diagnostic tests of medical conditions have several results. The rest result can be positive or negative. A positive test (+) indicates the patient has the condition. A negative test (-) indicates the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 137 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown.

Condition Present Condition Absent Row Total

Test Result + 119 18 137

Test Result - 18 46 64

Column Total 137 64 201

Assume that the sample is representative of the entire population. For a person selected at random, find P(getting test result - or condition present). Round your answer to the nearest hundredth
