Depends on what you call rogue (is it all a part of the grand plan?) but the galaxy is a huge place...SO I would say 100%....(new stars , cooling down have planets form and the orbits arent stable yet)...(In addition singularities / super novae can occur and begin to cause unstable orbits and drawing solar systems near to them inward etc...)
If you define 'rogue' as 'non stable orbit' then the odds of your question are 100%....
Although I have a feeling you meant solar system (instead of galaxy)....in which case that drops the odds to 0%, since the orbits of the planets and moons have all been relatively stable for a million years or more.
