If we want to know the number of star systems that the signal reached that have had planets in their habitable zones long enough for intelligent lie to develop, we multiply the total number by the fraction of star systems with planets, 0.50, and then by the average number of planets per planetary system that meet our criteria, 0.95. Nycz Nyt - NF MHz C X Use the fraction of the total star systems with planets and the fraction of those planets in the habitable zone to calculate the number of life-sustaining planets the signal
