Aperture Science works on top-secret transportation technology. Before testing the pollution technology began, Aperture was informed that such testing could cause illness in non-employees who live near its facility. It consulted experts who estimated that the monetary value of this illness would be $2.5 million, and Aperture spent $87,500 on precautionary safety measures. Now Aperture is being sued by families in the area who have doctors ready to testify that their illnesses occurred as a result of the testing. Using the Hand Rule, what must the probability of illness as a result of Aperture's research be for a court to likely find Aperture met the burden of care requirements? Round your answer to the nearest tenth of a percent.
