There are 19 students in Ms. Earl's’s class. They were discussing pets they have at home. When asked, "How many of you have dogs at home?", 14 students put up their hands. When asked "How many of you have cats at home?", 11 students put up their hands. When asked, "How many of you have both a cat and a dog at home?", 9 students put up their hands. How many students have neither cats nor dogs at home? Use a Venn diagram to help solve this problem. Be sure to explain your thinking clearly!
