The data in the table above were produced by a sleep researcher studying the number of dreams people recall when asked to record their dreams for one week. Group X consisted of 100 people who observed early bedtimes, and Group Y consisted of 100 people who observed later bedtimes. If a person is chosen at random from those who recalled at least 1 dream, what is the probability that the person belonged to Group $\mathrm{Y}^{\prime}$ ? A) $\frac{68}{100}$ B) $\frac{79}{100}$ C) $\frac{79}{164}$ D) $\frac{164}{200}$
