Chance outcome produced by sketch? (4,2,3,4)
I believe the answer is:
luck of the draw
'chance' is the definition.
(I have seen 'Sheer chance' mean 'luck of the draw' so perhaps 'chance' could also mean 'luck of the draw')
'outcome produced by sketch?' is the wordplay.
I cannot quite see how this works, but
'by' could be 'of' and 'of' is found in the answer.
'sketch?' could be 'draw' (to sketch is to draw) and 'draw' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for luck of the draw that I've seen before include "Chance, as in sweepstake" , "suggesting team should be thankful not to lose?" , "Result of complete chance" , "Chancy business" , "Sheer chance" .)
