comment Inequality with (1-x) as denominator
"I know it's wrong" You know the result is wrong, but do you know why the procedure is wrong? You can multiply both sides of an inequality by an expression (and keep the inequality) only if the expression is guaranteed to be positive.

comment Existing of a distribution of three random variables that have conditional mutual information with defined properties.
It's not necessary that the process is Markov for having an information decrease when conditioned - but it's indeed necessary if the decrease goes to zero. Proof added.

comment Guessing number in set 1-100 with weighted questions.
