At random (9)
I believe the answer is:
haphazard
'at random' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for haphazard that I've seen before include "Disorganised, random" , "Careless or random" , "Erratic" , "Slapdash, slipshod" , "Lacking any obvious organisation" .)
