Die 1 is an unbiased and regular six-sided die numbered 1 to 6.
Die 2 is an unbiased and regular seven-sided die numbered 2 to 8.
Die 3 is an unbiased and regular eight sided die numbered 3 to 10

Consider the quadratic equation Ax2+Bx+C= 0.

We assign values to the coefficient A by throwing Die 1, the coefficient B by throwing Die 2 and the coefficient C by throwing Die 3.

Determine the probability that the equation will have real roots.
