    I think you actually want {🐸}∪{🐘}⊂{🐂} because ∪ is union and ∩ is intersection. There are no frogs that are also elephants so the set would be empty and thus couldn’t contain any bulls. 😔

      Aktshually, the empty set is a subset of any other set 🤓

      But also, the fact that frogs and elephants are disjunct is conjecture at this point
