in a fast food joint, there are three varieties of milk foods (milk, yogurt, cheese), Three varieties of non-vegetarian food (mutton, chicken, fish), and three types of bread (white bread, brown bread, chappati). If a person chose one milk food, one non-vegetarian item and one variety of bread, how many different choices can he make?
