You can put this solution on YOUR website!
for this u need to make 3 circles that overlap in the middle\r
\n" ); document.write( "\n" ); document.write( "Top circle will be T for tutors
\n" ); document.write( "Left bottom circle will be C for Not Attending class
\n" ); document.write( "right bottom circle will be H for No homework\r
\n" ); document.write( "\n" ); document.write( "with all 3 circles drawn on paper, u will see the middle space is overlapped by all 3 circles. and 8 goes there because there were \"8 failed for all three reasons.\"
\n" ); document.write( "for circles T and C, 14 students were in common so 14-8=6 this fills in the portion that has only C and T overlapping
\n" ); document.write( "for circles T and H, 15 students were in common so 15-8=7 this fills in the portion that has only T and H overlapping
\n" ); document.write( "for circles H and C, 20 students were in common so 20-8=12 this fills in the portion that has only H and C overlapping\r
\n" ); document.write( "\n" ); document.write( "35 for not attending class in total
\n" ); document.write( "35-8-6-12= 9 students who only failed to not attending class
\n" ); document.write( "25 for not visiting tutors
\n" ); document.write( "25-8-7-6= 4 students who only failed to not visiting tutors
\n" ); document.write( "30 for not doing homework
\n" ); document.write( "30-8-7-12= 3 students who only failed to do homework\r
\n" ); document.write( "\n" ); document.write( "9+4+3+6+7+12+8= 49 students out of 65 total failures
\n" ); document.write( "so 65-49= 16 students that failed for other reasons\r
