The key to these Venn diagrams is to be able to find
\n" ); document.write( "the value of each of the little regions formed by the
\n" ); document.write( "intersection of 3 circles representing:
\n" ); document.write( "hotel on site = 24
\n" ); document.write( "wave pool = 38
\n" ); document.write( "water slide = 55
\n" ); document.write( "------------
\n" ); document.write( "There are 7 of these regions, an 1 of them is common to all 3
\n" ); document.write( "circles
\n" ); document.write( "The last statement says
\n" ); document.write( "\"7 of the amusement parks have all 3\", so you can label it.
\n" ); document.write( "You know that if you add up the 7 regions, you get 85
\n" ); document.write( "------------
\n" ); document.write( "Number the 6 regions that are left, and assign values that are given.
\n" ); document.write( "Remember that the area common to hotels and wave pools also
\n" ); document.write( "includes the center region common to all 3.
\n" ); document.write( "Good luck \n" ); document.write( "
