Two distinct numbers $a$ and $b$ are selected at random from $1, 2, 3, \ldots, 50$. The probability that their product $ab$ is divisible by $3$ is

Let $ f : [1,\infty) \to \mathbb{R} $ be a differentiable function. If
\[ 6\int_{1}^{x} f(t)\,dt = 3x f(x) + x^3 - 4 \] for all $ x \ge 1 $, then the value of $ f(2) - f(3) $ is
