Just show me the calculation where the probability is "easily greater than 10%". Well, the average no-hit avoidance streak is currently 10.86 years, so I don't think it's too far out of line using the rationale you used. Here's the data I used on that one. The original 10% was a very quick and dirty calculation I did on the fly assuming there being 3+ no-hitters per year and a 1 out of 30 chance of it being one specific team each time. I skewed it upward due to the offensive woes of the Cubs, even though the runs scored of teams that have been no-hit suggests that that doesn't really matter too much. Using your "post 2007" time frame, the CUBS have played 693 games and made 6,167 hits, or 8.90 hits/game. They have not been no-hit during that period, 1 hit once, 2 hit seven times.......

25 0 I didn't take the time to calculate the standard deviation for these 693 games, but I'd still like to see you try to get "easily greater than 10%" out of these numbers, eh? I'd like to think using the numbers relating to the overall occurrences of no-hitters would be a better approach, since we'd have to infer the nature of the distribution of hits per game and some more sophisticated math (oh no!).
