If an aircraft is present in a certain area, a radar detects it and generates an alarm signal with probability 0.9. If an aircraft is not present, the radar generates a (false) alarm, with probability 0.05. We assume that an aircraft is present with probability 0.1. What is the probability that the radar does not generate an alarm signal?
