but your answer covers that, thanks! ]]>

It's true only if p(x_i) is positive (for n=2).

Can we assume that p(Xs) is positive (i.e. Not zero) for every subset s of X1,…Xn at this question?

Shabbat Shalom!

]]>For two variables you have on the RHS

p(x_1)*p(x_2) * p(x_1,x_2) / (p(x_1)*p(x_2))

which is indeed p(x_1,x_2)

did you get something else? ]]>

Am I missing anything?

Just to be sure, the i in ij in E is the same i as in the first Pie_i=1?

Thanks!
