Jan 25, 2013 at 20:58 | comment | added | Aaron Meyerowitz | @SamHopkins. There are $38$ connected subgraphs of $K_4$. If I pick, choosing uniformly among them, and then pick uniformly among the spanning trees of that subgraph , then the probability of getting a star is 41/152. If I pick a spanning tree by randomly weighting the edges and then taking the minimal cost spanning tree then the probabilities are something else but almost surely not uniform. | |

Jan 25, 2013 at 0:03 | comment | added | Sam Hopkins | I assume you're considering labeled trees/graphs. Here's an answer for an easier version of the question, which maybe you have already considered: suppose you choose each connected graph on n vertices with equal probability, and suppose you choose from it a random spanning tree. Then it seems clear to me that all trees are equally likely. | |
