Technically yes, it's possible - but how likely depends on what you mean by 'without hitting 10 11 12':

1. None of the three numbers (10, 11, 12) hit at all in a game?
That's ~41% per game. Over 150 bets: (0.41)^150 ≈ 4.5 × 10⁻⁵⁹ — technically possible, but so astronomically unlikely that it's effectively impossible. You'll never see it.

2. All three numbers don't hit together (i.e., you never see 10, 11, and 12 in the same game)?
That's ~98.79% per game. Over 150 bets: (0.9879)^150 ≈ 16.1% — that's about 1 in 6. So this is absolutely possible and actually quite common.
