comment Number of Idempotent matrices.
It seems that there is no known general method to count such matrices. See: noetherian.net/ERAU/Conference/Abstracts/prescott_talk.pdf

comment Every random variable $X$ can be written as $X=\lambda Z_1+(1-\lambda)Z_2$, for $Z_1$ discrete and $Z_2$ continuous random variables.
Are you sure the "mixing" is done to the values of the random variables (and not to the densities or distribution functions)? That is, $X$ equals $Z_1$ with probablity $\lambda$ or $Z_2$ with prob $1-\lambda$ As stated, it doesn't make much sense to me.

comment Probability to draw two particular cards from a deck.
Your answer is right. I suggest that you double check the problem statement. Are we taking two cards?
