The NIH is creating a test for the Zika virus. The incidence of a Zika is low, 11 percent in the general population.There is a trial version, but it sometimes misses the disease.The probability of a false negative is 13 percent.Similarly, someone who does not have Zika, will sometimes get a positive reading.The probability of this is 10 percent.Fill in the tree diagram and ...

Answer in percent to 2 decimal places.
