2.Radioactive atoms are unstable because they have too much energy. When they release their extra energy, they are said to decay. When studying cesium-137, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed to 977,287 radioactive atoms. Assuming that the decay follows the Poission distribution, find its variance. Round your answer to the nearest tenth.
