Choose independently two numbers B and C at random from the interval [-1, 1] with uniform distribution, and consider the quadratic equation
x2 +Bx+C =0.
Find the probability that the roots of this equation
(a) are both real.
(b) are both positive.
Hints: (a) requires 0 = B2 - 4C, (b) requires 0 = B2 - 4C, B = 0, 0 = C.
