For a recent evening at a small, old-fashioned movie theater,40%
of the moviegoers were female and60% were male. There were two movies playing that evening. One was a romantic comedy, and the other was a World War II film. As might be expected, among the females the romantic comedy was more popular than the war film:75%
of the females attended the romantic comedy. Among the male moviegoers the romantic comedy also was more popular:55%
of the males attended the romantic comedy. No moviegoer attended both movies.
