\textbf{148-} In the equation $ax^2 + bx = 5$, coefficient $a$ is chosen randomly from the interval $[1,3]$ and coefficient $b$ is chosen randomly from the interval $[-3, 0]$. With which probability is the set of solutions of this equation more than $\dfrac{2}{3}$?
$$\frac{4}{9} \ (1) \hspace{2cm} \frac{5}{9} \ (2) \hspace{2cm} \frac{7}{12} \ (3) \hspace{2cm} \frac{5}{6} \ (4)$$
