In this paper, we employ Riemann-Liouville fractional integrals to derive two primary integral findings concerning the ?-pre-Gr?ss inequality and the (?, ?)-pre-Gr?ss inequality. Our results extend existing integral inequalities reported in the literature. Additionally, we discuss some applications of our results for continuous random variables (CRV, for short) with bounded probability density functions. Some new estimates are provided in this context, along with classical results obtained as special cases from our results.
