Description: Three radar sets, operating independently, are set to detect any aircraft flying through a certain area. Each set has a probability of. 02 of failing to detect a plane in its area. If an aircraft enters the area, what is the probability that it a. goes undetected? b. is detected by all three radar sets?

Key Concepts

Independent Events

This concept refers to events that do not affect each other’s outcomes. When events are independent, the occurrence of one does not influence the occurrence of another, which allows for the simple multiplication of individual probabilities to find the combined probability of multiple events occurring simultaneously.

Multiplication Rule

The multiplication rule states that the probability of all independent events occurring together is the product of their individual probabilities. This rule is crucial when calculating the likelihood of a series of successes or failures in scenarios where events occur independently.

Detection Probability

Detection probability is the measure of the chance that a system or device successfully identifies a target or signal. In reliability and quality analysis, it is often important to consider both the probability of detection (success) and the probability of failure (non-detection) when evaluating performance.

Complementary Probability

Complementary probability is the concept that the sum of the probability of an event and the probability of its complement (the event not occurring) is equal to one. This is useful in many problems to determine the chance of failure, given the probability of success, or vice versa.
