-There are four different kinds of radar systems designed to detect or monitor the airspace around a major airport for high-flying objects, low-flying objects, runway traffic, and wind shear. Each operates independently from the others. If each system has probability 0.90 of functioning correctly, find the probability at least one radar system will fail.
