- What is the probability that a registered voter voted in the election? The probability that a registered voter voted in the election is approximately. (Round to three decimal places as needed.) About 3,034,053 voted in the election About 3,529,477 of the registered voters did not voteRadioactive Decay 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, so 22,713 atoms decayed during 365 days. a. Find the mean number of radioactive atoms that decayed in a day. b. Find the probability that on a given day, 50 radioactive atoms decayed.BlueSky Air has the best on-time arrival rate with 75% of its flights arriving on time.
