    You need to give us more information. *Some* binary systems? How many? Just one binary, or multiple binaries?

    Do you know the magnitudes of the individual stars in the binary or binaries?
  4. Yeah, suppose we know the magnitude of all the stars and that the number of binary systems is k (can be one or more).
