comment Probability that a random integer matrix is invertible
@Nicholas Thanks, your arguments seem valid. I guess that my professor went mad!

comment Probability that a random integer matrix is invertible
Nicholas, it can't be true for a bounded subset because there exist non-invertible matrices and the chance to get uniformly a specific matrix (when the set is bounded) is more than zero. I am sure that the distribution was meant to be uniform. Are you sure there is no alternative definition for uniform distribution over infinite set? I come from computer science and we don't have the highest mathematical formality.

comment If $x \sim U(Z_n^*)$ then $x^2 \pmod n\sim U(QR_n)$?
@Derek Holt, Thank you! This is an exact and complete answer to my question (in 3 parts). It would be nice to copy it as an answer so I can officially accept it (only if you want). and again, Thank you.
