I'd rather you answer these each on their own rather than trying to derive (if it's even possible) some from the others, so that the results aren't contaminated in that way by the order in which I've asked them.

Probabilities for this are from 0 to 1; 0=zero chance, 1=certain.

P('Qualia of purple' is a coherent and meaningful and non-epiphenomenal concept | 'Qualia of consciousness' is a coherent and meaningful and non-epiphenomenal concept)

Likelihood of same event, but conditioning on negation:

P('Qualia of purple' is a coherent and meaningful and non-epiphenomenal concept | 'Qualia of consciousness' is an incoherent or non-meaningful or epiphenomenal concept)

Conversely:

P('Qualia of consciousness' is a coherent and meaningful and non-epiphenomenal concept | 'Qualia of purple' is a coherent and meaningful and non-epiphenomenal concept)

and conditioning on negation:

P('Qualia of consciousness' is a coherent and meaningful and non-epiphenomenal concept | 'Qualia of purple' is an incoherent or non-meaningful or epiphenomenal concept)

Cheers!
