Question 320025: The Wildlife Federation surveyed 220 San Diego residents. The results are as follows:

32 had a membership to the Birch Aquarium
57 had a membership to the San Diego Zoo
21 had both

Answer the following questions:

i. How many had only a zoo membership?
ii. How many had only an aquarium membership?
iii. How many belonged to either one or the other or both?
iv. How many belonged to neither?
***Also, construct a Venn diagram

You can put this solution on YOUR website!
i. 32 - 21 = 11
ii. 57 - 21 = 36
iii. 11 + 36 + 21 = 68
iv. 220 - 68 = 152
The venn diagram would use overlapping circles not pictured
Aquarium Both Zoo
36 21 11
Both would be in the overlapping area.
