If I got one that was sold as "het hypo", I could get any kind of ghost aside from the two you said, and I should get ghosts and hets, but not double hets?
Exactly, if you got a Hypo and het Hypo you should get in theory half of the clutch Hypos and the other half 100% het Hypos. But if you have great odds, you could get all Hypos.
