We calculate the average numbers of closed, flat, and open universesspontaneously created from nothing in third quantization. The creation ofuniverses is exponentially suppressed for large values of the kinetic energy ofthe inflaton, while for small kinetic energies it is exponentially favoured forclosed universes over flat and open ones: For a scale of inflation less thanabout $2 \times 10^{16}$GeV, the ratio of the number of closed universes toeither the number of flat or open universes is \begin{equation}\frac{n_{closed}}{n_{flat,open}} \gtrsim 10^{10^{10}} . \nonumber\end{equation}
