26 students 15 like vanilla 16 like chocolate. 3 do not like either flavour. How many like both vanilla and chocolate

Define our people:

1. We have Vanilla Only
2. Chocolate Only
3. Both Vanilla and Chocolate
4. Neither Vanilla Nor Chocolate
5. Add up 1-4 to get our total

Total = Vanilla Only + Chocolate Only - Vanilla and Chocolate + Neither
26 = 15 + 16 - V&C + 3
26 = 34 - V&C

Subtract 34 from each side
-V&C = -8

Multiply each side by -1
V&C = 8
