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

There is no known physical reason for the value of F1F1F1S1F1F1F10_mass F1F1F1S1F1F1F10 F1F1F1S1F1F1F10F1F1F1S1_F1F1F10 F1F1F1S1F1F1F10 to be exactly 0.9, so the value being precise would be very improbable.
