how you get the probability???

when c fixed,

we can compute the probability distribution
of M from the known joint probability distribution
of M, and C. (there is only one joint probability
distribution, there is no such thing as the joint
probability distribution of M and C when C is fixed)
We find that the probability distribution
of M is not uniform.


if we soppose k uniform, then m uniform

and as we know that M is not uniform we conclude that
the assumption that K is uniform when C is fixed
is incorrect.
