Recently a student and I talked about the probability of the roots a
quadratic equation (AX^2 + B*X + C) to be complex. As we all know, the
roots will be complex if (B^2-4*A*C) is less than zero.
Can someone please explain why three (uniformly distributed) randomly
chosen numbers, A, B, C
Uniformly distributed, eh? On an infinite space?
How does that work?
