\n" ); document.write( "Sketch 2 intersecting cirecles
\n" ); document.write( "The intersecting section is 24%
\n" ); document.write( "The remaining section of the muffin circle is 30-24 = 6%
\n" ); document.write( "The remaining section of the coffee circle is 80-24 = 56%
\n" ); document.write( "The section outside both circles is 100-(6+24+56) = 14%
\n" ); document.write( "-------------------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "a. Purchase either a coffee or a muffin or both?:: 86%
\n" ); document.write( "b. Do not purchase either?:: 14%
\n" ); document.write( "c. Purchase only a coffee but not a muffin?::56%
