Nick,

Somehow I don't relate to the sandwich case.  Is having ham and having eggs
different from having ham and eggs.

Your second question may be related to the following:  if A and B are both
causes of C then A and B are not independent given C.  Let C be "car
starts", A be "gas in tank" and B be "battery charged".  If you know
there's gas in the tank and you observe that the car starts then you infer
whether the battery is charged.  There are numerous ways to object to this
which are irrelevant.  "What if the spark  plugs are missing?"  Etc.
