\n" ); document.write( "All this involves is the number of groups of 2 that can be formed by 12 people, and as person 1 doesn't shake
\n" ); document.write( "hands with him/her self, and since person 1 shaking hands with person 2 is the same as person 2 shaking hands
\n" ); document.write( "with person 1, order is UNIMPORTANT, thereby leading to the calculation of the combination of 12 persons,
\n" ); document.write( "choosing 2, or \"_%5B12%5DC%5B2%5D\", or \"highlight_green%28highlight_green%2866%29%29\" handshakes. \n" ); document.write( "
\n" );
