28 rolls in a row without a 10? Something is fishy..
Roll 2 dice 30 times. You can eventually get the same result.
There is about 9% [100%*(1-(3/36))^28] chance you will not get a 10 in 28 rolls. So on average this will happen to you once in eleven games.
on a 10 yes, is understandable but on 8 or 6 the odds are a bit different and I didn't count the number of rolls but they were a lot
