The data represents the results for a test for a certain disease. assume one individual from the group is randomly selected. find the probability of getting someone who tests negative, given that he or she had the disease. the probability is approximately? ( round to three decimal (places as needed.)positive yes. no 137 8negative 16 139

Step-by-step explanation: Rewriting the table

Yes  |     137           |             8           |   145

No    |       16           |            139        |    155

Total |     153           |            147        |   300

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

P(Negative | Yes) = P(Negative ∩ Yes) = 8

                                        P(Yes)              145
