Plans to search for incoming radio waves from extraterrestrial civilizations are discussed, focusing on the probability of a successful search. The program consists of a targeted search, focusing on about 1,000 closer stars using large radio telescopes and covering the region from 1.2 to 2.0 GHz with a frequency resolution of 1 Hz, and an all-sky survey using small radio telescopes and covering the region from 1 to 10 GHz with a frequency resolution of 32 Hz. The very long search time and signaling time necessary for a successful search is examined in detail. The probability of success is studied numerically, based on factors such as the rate of star formation, the rate at which technological civilizations could form, signaling time, and search time.
