Why would it be very improbable for our universe to have $\varOmega$_mass+ $\varOmega$_$\wedge$ = 0.9? A) It would quickly evolve to have a much different value of $\varOmega$_mass+ $\varOmega$_$\wedge$. B) In order to exist,every universe must have $\varOmega$_mass+ $\varOmega$_$\wedge$ = 1. C) We know $\varOmega$_mass= 1,based on the average density of galaxies. D) The fluctuation in the CBR tells us that $\varOmega$_mass+ $\varOmega$_$\wedge$= 0.7.

It is highly unlikely that a universe with a specific value for mass, energy density, and cosmological constant would have a stable set of physical laws that would permit life as we know it to exist. Any such universe would be unstable and quickly evolve to have a much different value of these parameters.
