# Resonating quadratics

**Discrete Mathematics**Level 4

Two numbers \(b\) and \(c\) are chosen at random (with the replacement from the numbers \(1,2,3 \ldots 9\) ) . The probability that \(x^{2} + bx + c > 0\) for all \(x \in R\).

\(\text{Details and Assumptions :-}\) Let the probability could be represented as \(\dfrac{A}{B}\) ,then find \(A+B\) .
