Use computer simulation to find the probability that the quadratic equation Ax2 + Bx + C = 0 has real roots when A, B, and C are chosen at random from the interval (-q, q), independently of each other. Also, use simulation to find this probability when A, B, and C are nonzero integers that are chosen at random between -q and q, independently of each other. Vary q as 1, 10, 100, 1,000, and 10,000.
