Subtrees of a Given size in Schroeder Trees
arXiv:1904.05525
Abstract
In this paper we find the generating function for the number of vertices which have elements in their subtree and use this generating function to calculate the probability that a vertex has a size subtree. We also show how this same technique can be applied to calculate the probabilities for other trees and specifically apply it to Motzkin trees.
