What distribution gives more weight to the most likely estimate?

The Beta Distribution (PERT) gives more weight to the most likely estimate because it allows for greater flexibility in specifying a mode (a single most likely estimate) and skewness (asymmetric distribution). In contrast, the normal distribution is symmetric and places equal weight on all possible estimates. The triangular distribution is also symmetric but has a different weighting pattern than the normal distribution. Lastly, the uniform distribution assigns equal weight to all possible estimates and does not favor one estimate over another.
