\n" ); document.write( "The other circle has 32 in it that wear jeans
\n" ); document.write( "-----------------
\n" ); document.write( "The intersection has 15 in it that wear both
\n" ); document.write( "-----------------
\n" ); document.write( " $\"+21+-+15+=+6+\"$ is the number that wear
\n" ); document.write( "t-shirts but not jeans
\n" ); document.write( " $\"+32+-+15+=+17+\"$ is the number that wear
\n" ); document.write( "jeans but not t-shirts
