Query: Symmetric generalized binomial distributions   In two recent articles we have examined a generalization of the binomial
distribution associated with a sequence of positive numbers, involving
asymmetric expressions of probabilities that break the symmetry {\it win-loss}.
We present in this article another generalization (always associated with a
sequence of positive numbers) that preserves the symmetry {\it win-loss}. This
approach is also based on generating functions and presents constraints of
non-negativeness, similar to those encountered in our previous articles.
