A toss-up offers faint prospect (4,3)

I believe the answer is:

pass out

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

'faint prospect' is the definition.
'pass out' can be an answer for 'faint' (synonyms). I'm not certain of the 'prospect' bit.

'a toss-up' is the wordplay.
'a toss-up' anagrams to 'PASS OUT'.
But, I'm unsure how this is indicated.

'offers' acts as a link.

Can you help me to learn more?

(Other definitions for pass out that I've seen before include "Become unconscious" , "In the army, do so having proved ready" , "Lose consciousness" , "drop" , "keel over" .)
