Abstract
Let $X_{d_1, d_2}$ be an $F$-random variable with parameters $d_1$ and $d_2,$
and expectation $E[X_{d_1, d_2}]$. In this paper, for any $\kappa>0,$ we
investigate the infimum value of the probability $P(X_{d_1, d_2}\leq \kappa
E[X_{d_1, d_2}])$. Our motivation comes from Chv\'{a}tal's theorem on the
binomial distribution.
