There's no way of telling. I'll guess you didn't, but that's a guess about people, not about sequences of digits. See, it's not about how likely it is that OP rolled 123456123456; it could have been any "unlikely" number (where I suppose "unlikely" is a psychological quality). So OP keeps rolling until an "unlikely" number comes up, and exclaims "Wow, how unlikely was that?". Well, it's impossible to know, without knowing how many "unlikely" numbers there are; but it's much more likely than 123456123456 is. Aren't all sequences really equally unlikely? So whatever you roll, it's as improbable as all-1s?
