Possible to find out good arrangement of sublease (9)

I believe the answer is:

guessable

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

'possible to find' is the definition.
I can't judge whether this definition defines the answer.

'good arrangement of sublease' is the wordplay.
'good' becomes 'g' (abbreviation).
'arrangement of' indicates anagramming the letters.
'sublease' is an anagram of 'uessable'.
'g'+'uessable'='GUESSABLE'

'out' acts as a link.

Can you help me to learn more?

(Another definition for guessable that I've seen is " Worth a stab at such an answer?".)

I've seen this clue in The Times.
