I was just wondering if my representation of the first and second rules are correct:
Jaclyn → Lorena (Contrapositive: Lorena → Jaclyn)
Lorena → Jaclyn (Contrapositive: Jaclyn → Lorena)

So the first rule indicates that both can't be on stage, and the second rule indicates that at least one is on stage (since both can't be on stage as stated in the first rule). So this is a bi-conditional in the form of A or B, but not both (A or B but not otherwise) which means either A is selected without B, or else B is selected without A:

Jaclyn ↔ Lorena
Jaclyn ↔ Lorena

Would this be right? So Jaclyn or Lorena is always in, and Jaclyn or Lorena is always out.
