Joy is going to a sub shop for a sandwich. At the restaurant, she can choose either a roll (R), bread (B), or a wrap (W). There
are two meat choices, ham (H) and turkey (T), and 2 kinds of cheese, Swiss (S) and American (A). Before she goes, Joy wants to make a list of her choices. If she chooses one item from each selection, which will be part of her list?
