The table below displays results from experiments with polygraph instruments. The task is to find the positive predictive value for the test, which is the probability that the subject lied, given that the test yields a positive result.

|                          | Did the Subject Actually Lie? |
|--------------------------|-------------------------------|
|                          | No (Did Not Lie) | Yes (Lied) |
| Positive test results    | 14               | 42         |
| Negative test results    | 30               | 8          |

The probability is [_____] (Round to three decimal places as needed.)
