**drwls**, Monday, November 29, 2010 at 12:06amThe question needs to be more clearly worded.

If those 8 owning a cat includes those that may also also own a dog, and those 15 owning a dog include those that might own a cat, then there are 15 + 8 -5 = 18 with a dog or a cat or both. That leaves 12 with neither.

There is another way the question could be interpreted. The eight might own ONLY cats and the 15 might own only dogs, with an additional 5 owning both. Then you get a different answer.

**MattsRiceBowl**, Monday, November 29, 2010 at 12:15amThere are also students that own neither. The questions are not written well. Do you have an example of one the teacher did so we have something to work from to know what (s)he is asking?
