The Venn diagram shows the number of patients seen at a pediatrician’s office in one week for colds, C, ear infections, E, and allergies, A.

Circles C, E, and A overlap. Circle C contains 4, circle E contains 9, and circle A contains 15. The overlap of C and A contains 2, the overlap of C and E contains 10, and the overlap of E and A contains 3. The overlap of the 3 circles contains 1. Number 5 is on the outside of the circles.

How many patients had allergies or ear infections, but not both?

Reason: Count those with A but not E (only A 15 + A∩C only 2 = 17) and those with E but not A (only E 9 + E∩C only 10 = 19). Sum = 17 + 19 = 36.
