The part of defective transistors made by a factory is 10 percent. Technicians of the factory are using meters to test transistors. The technicians find defective transistors with a probability of 0.95.A technician can mistakenly test a good transistor and assume that it is defective with a probability of 0.05.If a transistor is considered defective after it was tested by a technician, what is the probability that the transistor is actually defective?(Use the Bayes' formula).
