Interpret the Venn diagram to answer the questions about the doctors and the animals they treat.
Understand the Problem
The question involves interpreting a Venn diagram to analyze the workload of veterinarians at an animal sanctuary. It requires identifying which doctors treat specific animals (iguanas), the number of animal types treated only by one doctor (Dr. Barnes), and animal types treated by only one of the three doctors.
Answer
(a) Dr. Barnes, Dr. Jackson, Dr. Hill (b) 2 (c) Birds, Cats, Elks, Frogs, Koalas, Otters, Pigs, Quails, Rabbits

(a) Dr. Barnes, Dr. Jackson, Dr. Hill (b) 2 (c) Birds, Cats, Elks, Frogs, Koalas, Otters, Pigs, Quails, Rabbits
Steps to Solve
-
Identify Doctors Who Treat Iguanas Look at the Venn diagram and find where "Iguanas" is located. Note which circles overlap in that region.
-
Count Animal Types Treated Only by Dr. Barnes Identify the region of the Venn diagram that belongs only to Dr. Barnes' circle (i.e., it does not overlap with any other circles). Count the number of animal types listed in that region.
-
Identify Animal Types Treated Only by One Doctor For each animal type listed in the options for part (c), check the Venn diagram to see if it falls within a region belonging to only one of the three doctors. Select all that apply.
(a) Dr. Barnes, Dr. Jackson, Dr. Hill (b) 2 (c) Birds, Cats, Elks, Frogs, Koalas, Otters, Pigs, Quails, Rabbits
More Information
Venn diagrams are a useful way to visualize the relationships between different sets of data. In this case, they help represent which doctors treat which animals.
Tips
- Failing to recognize that the area where the three circles overlap means that all three doctors treat those animals.
- Miscounting the number of animal types in a specific region of the Venn diagram.
- Selecting additional animal types which are treated by more than one doctor.
