Venn Diagram - The Silversnake class, the Jellyfish class, and the
Radical Dog-Star class (kindergartners and first- and
second-graders) were talking about their favorite field trips
during the school year. One of the teachers, Ms. Burke, turned the
discussion into a math lesson, and the students conducted a survey.
Each child wrote down on paper which trip was his or her favorite.
(Note that many children named more than one field trip as their
favorite.) The survey revealed that 52 wrote down the trip to the
river, 50 indicated the trip to the police station, and 44 included
the trip to the hardware store. The police station and the river
were chosen on 19 papers, 32 papers included both the river and the
hardware store, and 25 children wrote down the police station and
the hardware store on their papers. Ms. Burke counted 17 papers
that included all three and one that did not list any of the three
trips. How many children were surveyed? How many children wrote
down the river but not the police station? How many children did
not list the hardware store?
