comment Generalized expression for balls and bins problem
If there are two bins and one ball is thrown into them with uniform probability, are you expecting the answer to be $1/2$ (the average number of balls per bin) or $1$ (the average number of balls among the set of bins with at least one ball)?

comment Surjective marriages
Yes, there's no right to expect matchings from $M$ to $W$ to be bijective once the graph is infinite.
