Roots Of The Equation (Posted on 2003-08-20) Difficulty: 3 of 5

We assign values to the coefficients a, b and c by throwing a die.

What is the probability that the equation will have real roots ?

Yes Gamer, I had said that when the problem was in the queue and there were a few doubts regarding the real roots or may be something else. So I had posted a comment saying that the condition for the existence of real roots means the vanishing of the discriminant.
