If $G$ has the additional property that every $H$-decomposable subgraph of $G$ is part of an $H$-decomposition of $G$, then $G$ is randomly $H$-decomposable. Using computer assistance, we provide in this paper a characterization of randomly path-decomposable graphs for paths of length 11 or less. We also prove the following two results: { indent=7mm \item{(1)}With one small exception, randomly $P_{k}$-decomposable graphs with a vertex of odd degree do not contain a $P_{k+1}$-subgraph, \item{(2)} When the edges of a $P_{k}$-subgraph are deleted from a connected randomly $P_{k}$-decomposable graph, the resulting graph has at most one nontrivial component. }}, identifier = {06099139}, }
