BioTech Research Center is working to develop a new vaccine for the West Nile Virus. The project is so important that the firm has created three teams of experts to work on the project from different perspectives. Team 1 has a 83 percent chance of success, team 2 an 80 percent chance of success, and team 3 a 94 percent chance. What is the probability that BioTech will develop the vaccine?  (Round answer to 4 decimal places, e.g. 15.2500.)
