Help I can't figure this out. I don't know what kind of diagram I should use.I tried a Venn diagram but it didn't work.

Ellen baked 2 dozen cupcakes of which half contained chocolate, two-thirds contained raisins, one-fourth contained chocolate chips, and one-sixth contained nuts. What is the largest possible number of cupcakes that had none of these ingredients?
