Question

an animal sanctuary houses a variety of animals. to understand the workload of the sanctuarys veterinarians, the director looked at which types treated or not treated by various doctors. the venn diagram shows this information for three of the doctors. (a) select all the doctors who do not treat iguanas. dr. anderson dr. king dr. jackson (b) how many types of animals are treated by dr. anderson or dr. jackson (or both)? (c) which types of animals are treated by neither dr. anderson nor dr. king nor dr. jackson? choose all that apply. cats dogs elks frogs goats horses iguanas llamas mice pigs quails rabbits zebras

Explanation:

Step1: Analyze part (a)

Check the Venn - diagram for iguanas. Iguanas are in the intersection of Dr. Anderson and Dr. King's circles. So Dr. Jackson does not treat iguanas.

Step2: Analyze part (b)

Count the distinct types of animals in Dr. Anderson's and Dr. Jackson's circles (including the intersection). Animals are dogs, elks, llamas, quails, horses, mice, so there are 6 types.

Step3: Analyze part (c)

Look for animals outside all three doctors' circles. Frogs, goats, zebras are not in any of the circles of Dr. Anderson, Dr. King, or Dr. Jackson.

Answer:

(a) Dr. Jackson
(b) 6
(c) Frogs, Goats, Zebras
