Research questioin on sets

[poonamchiK]

Hi guys,
I am so sorry to post here, but am unable to find a solution to my research question. I would really appreciate if some1 can make a set for me. I have tried to rack my brains on this one, but am unable to come to a conclusion:

There are 17 participants to a research. 12 have headaches, 14 have neckaches and 5 have dizzyness.
9 had both headaches and neckaches. 4 had neckache and dizzyness. 5 had dizziness and headache (That means all of the ones who had dizziness also had headaches). 4 had all 3.

Do you guys think this can be fit in a set? This is how my patients have given me a history.

All help is appreciated

if this is not a problem from the free GMAT PREP software, this is the wrong folder.

please post the problem in the correct folder.
if it's from a source other than GMAT PREP or MPrep, then it belongs in the general math folder with a citation of the original source.

thanks.
