Math

This is a Venn Diagram on the number of students who prefer different boy or girl bands, that is, Coboy Junior, One Direction and Girls' Generation. The number of students in my class is 17, 10 girls and 7 boys. One Direction is denoted with an A. So the number of people overall who loves One Direction is n(A)= 5 and the members of A= {Tracey, Kevin, Anand, Alghiery, Joshua}. Girls' Generation is denoted with a B. So n(B)= 2, consists of: B= {Fellingga, Ruth}. And Coboy Junior(C): n(C)= 0 and consists of C= {} or null set. There are also students who love 2 or 3 bands at once like Jayanti and Aminy who love both Coboy Junior and Girls' Generation, Vivy who likes One Direction and Girls' Generation. There are also students who love all of the bands, like Fakhruni, Gloria and Michael, and students who like neither, like Felix, Shevalda and Putra.
