Given: the universal set = {all animals}; a = {hogs}; b = {cows}; c = {horses}; d = {foals}; e = {mares}. click on the diagram until you find the one that correctly represents the expression. (note: mares are female horses, foals are baby horses).

The universal set will contain all of the sets, A, B, C, D and E.

Next, because hogs, cows and horses are different animals, they will all be in separate, non-overlapping sets.

Finally, D and E are types of horses so they will be complete contained within set C. Note that a baby horse may either be male or female, so the set D and set E will overlap.
