Got stuck at this problem for a long time

The fact that the parameters are binary means that there is a finite number of parameters. So for example for P(a) if a was binary, then one parameters is enough to characterize it. For a normal binary variabled distribution of the form P(a,b,c), there should be 2*2*2 - 1 = 7 parameters. However I don't know how the factorization would affect the number of parameters.
