Multiple Choice

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 128 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. Assume that the sample is representative of the entire population. For a person selected at random, find P(getting test result + and condition present) . Round your answer to the nearest hundredth.
$$\begin{array} { l c c r } & \text { Condition Present } & \text { Condition Absent } & \text { Row Total } \\\text { Test Result } + & 107 & 21 & 128 \\\text { Test Result } - & 21 & 45 & 66 \\\text { Column Total } & 128 & 66 & 194\end{array}$$
