Let a and b be chosen at random from {0,1,2,3,4,5,6,7,8,9}.

Find the probability that x^2 + ax + b^2 = 0 will have
at least one real solution.

Another way of expressing the equation is that there is a valid solution when b <= sqrt(a).

For the number sets given, this occurs 26 out of 100 combinations.

Answer: 26 %
