probably

I'm a little stuck... Click here to teach me more about this clue!

'chances are' is the definition.
('chances are...' means 'probably')

(Other definitions for probably that I've seen before include "Most possibly" , "Likely" , "In all likelihood" , "No doubt" , "I expect so" .)

I've seen this clue in The Guardian.
