I guess that my professor went mad! May 28 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.

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.
