In a survey of 920 people aged from 18 through 84 years, of whom 84 belonged to the Millenial Generation, 224 belonged to Generation X, 200 belonged to the Baby Boom Generation, and the rest belonged to the Silent Generation, the following question was asked: Who has slept with a cell phone nearby? Of those who answered in the affirmative, $83 \%, 68 \%, 50 \%$, and $20 \%$ were from the Millenial Generation, Generation X, the Baby Boom Generation, and the Silent Generation, respectively. If a person in the survey is selected at random and has not slept with a cell phone nearby, what is the probability that the person belongs to the Millenial Generation? Source: Pew Research Center.
