Venn diagrams depict the similarities and differences between two concepts visually. The number of patients that had allergies or ear infections, but not both are 24.
What is the Venn diagram?
A Venn diagram is used to understand a large sum of data about a small population or sample visually with ease. It shows the difference and similarities between the sampled space.
As we can see in the given Venn diagram,
The number of patients that only had allergies = 15
The number of patients that only had ear infections = 9
Therefore, the number of patients that had allergies or ear infections, but not both can be written as,
= The number of patients that only had allergies + The number of patients that only had ear infections
= 15 + 9
= 24
Hence, the number of patients that had allergies or ear infections, but not both are 24.
