Have time for policies beginning to show probability (10)

'probability' is the definition.
(likeliness is a kind of probability)

'have time for policies beginning to show' is the wordplay.
'have time' becomes 'like' (I can't justify this - if you can you should believe this answer much more).
'for' says to put letters next to each other.
'policies' becomes 'lines' (as in a party line, a political policy or view).
'beginning to' indicates taking the first letters.
The initial letter of 'show' is 's'.
'like'+'lines'+'s'='LIKELINESS'

Can you help me to learn more?
