The non primes add up to 37.............the primes add up to 28..............again..........3 + 7 = 10..........2 + 8 = 10...........if u divide the non primes by the primes............u get 1.321429.............and vice versa..........the primes by the non primes..............u get a little over 75 %..............0.756757.................75 and 57...........reflexive sym..................13.........the next prime after 11...........

28	0.756757
37	1.321429
