| Abstract: |
| Motivated by Chvátal's theorem, in this paper, we consider the infimum value problem on the probability that a random variable is at most its expectation. By employing the analytical method, the results for a random variable with the Weibull distribution or the Pareto distribution are obtained. |
| Key words: Chvá tal's theorem Weibull distribution Pareto distribution |
