Answer: 8/145

Step-by-step explanation: Rewriting the table

Positive and Negative stand for the result of the test

Yes and No stand for having the disease

          Positive       |      Negative     | Total

<u>Yes </u><u>  |     137           |             8           |   145</u>

<u>No  </u><u>  |       16           |            139        |    155</u>

<u>Total</u><u> |     153           |            147        |   300</u>

<u />

probability of getting someone who tests negative, given that he or she had the disease.

P(Negative | Yes) = <u>P(Negative ∩ Yes)</u> = <u> 8 </u>

                                        P(Yes)              145
