Suppose that *A* is the set of sophomores at your school and *B* is the set of students in discrete mathematics at your school. Express each of these sets in terms of *A* and *B*.

**a)** the set of sophomores at your school who are not taking discrete mathematics

**b)** the set of students at your school who either are sophomores or are taking discrete mathematics

**Solution**

**a)** the set of sophomores at your school who are not taking discrete mathematics

**b)** the set of students at your school who either are sophomores or are taking discrete mathematics

*A*∪*B*
