Of the 30 students in my class, 11 practice taekwondo, 11 play piano, and 20 take lessons at MS. 4 students play piano and go to MS, 3 students do taekwondo and play piano, 5 students go to MS and practice taekwondo, and 3 students do none of these. How many students do all 3?
+36916 Are you sure you posted the numbers correctly? In particular the 20 number.....but it could be oneof the others....is there only 30 students?
The numbers don't add up....here is a Venn Diagram (bottom nember is 13)
