Answer 2

Option B. 28

Explanation:

In this question we have to find the total patients who were seen only for a cold, only an ear infection and only allergies.

From Venn diagram we find that patients seen for only a cold C = 4

Patients seen only for an ear infection E = 9

And patients seen for only allergies A = 15

So total patients = C + E + A = 4 + 9 + 15 = 28

Option B. 28 is the correct answer.
