Roots Of The Equation (Posted on 2003-08-20) Difficulty: 3 of 5
Let us consider the quadratic equation: ax˛ + bx + c = 0.

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 ?

Well Talon, the two words 'Discriminant' and 'Determinant' are two different things and not the same. In this problem you need the former and not there's no use of the latter one. Secondly I did not mean to say that the number vanishes but the discriminant vanishes, that is the expression under the 'square root'.
