Burl EE 3180 Probability and 11 EE 3180 Probability and Conditional Probability n Conditional probability is very frequently used in signal processing. n Probability that an airplane is at a given distance given a received radar signal. n Probability of alternator failure given a current output measurement. n Typical to measure something to infer EE 3180 Probability and 22 EE 3180 Probability and Conditional Probability via Set Theory n The conditional probability of A given B is defined: n Note that if A and B are elementary events: n But A and B do not have to be elementary events.
