if an aircraft is present in a certain area, a radar generates an alarm signal with probability 0.99. if an aircraft is not present, the radar generates an alarm with probability 0.1. Assume that an aircraft is present with probability 0.5. a) what is the probability an aircraft is present and there is no alarm? b) what is the probability that an aircraft is present, given that an alarm was signalled?

Three radar sets, operating independently, are set to detect any aircraft flying through a certain area. Each set has a probability of 0.04 of failing to detect a plane in its area. Consider one of the radar sets. What is the probability that it will correctly detect exactly three aircraft before it fails to detect one, if aircraft arrivals are independent single events occurring at different times? (Round your answer to four decimal places.)

Three radar stations, operating independently, are set to detect any aircraft flying through a certain area. Each station has a probability of 0.85 of detecting a plane in its area. If an aircraft enters the area, a. what is the probability that it is detected by all three radar stations? b. what is the probability that the plane is not detected by any of the radar stations? c. what is the probability that the plane is detected by only one...

No (Baye's Theorem) A carbon monoxide (CO) detector can detect the presence of CO with 95% probability if there exist trace amounts of CO. However, it gives a false alarm with 5% probability when no CO is present. This detector is employed to inspect furnaces for leakage of CO, Assume that 1% of furnaces have a CO leakage problem. a. Find the total probability that the detector gives an alarm when a furnace is randomly checked. b. Find the probability...

3. Let C be the event that a patient suffers from a certain condition, and let T denote a positive result from a lab test that is designed to detect the presence of said condi- tion. Suppose that the proportion of the population that actually has the condition IS E E (0,1). Additionally, suppose that, when the condition is actually present in a patient, the test is positive with probability a (0,1). On the other hand, when the patient does...

4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
