A class has 175 students. The following data shows the number of students taking one or more subjects. Mathematics 100, Physics 70, Chemistry 40; Mathematics and Physics 30, Mathematics and Chemistry 28, Physics and Chemistry 23; Mathematics, Physics and Chemistry 18. Use a venn diagram to show how students are taking maths alone
Students_taking_math_only = Math - Math&Phys - Math&Chem + Math&Phys&Chem = 100 - 30 - 28 + 18 = 60
