Scraps inequality (4)
I believe the answer is:
odds
This clue is a double definition.
'scraps' is the first definition.
(thesaurus)
'inequality' is the second definition.
(I've seen this before)
(Other definitions for odds that I've seen before include "Measure of probability" , "inequality" , "The chances of something happening" , "ten to one?" , "Likelihood of something happening" .)
