Happy at not having to toss a coin about it (7)
I believe the answer is:
'happy' is the definition.
(associated in meaning)
'not having to toss a coin about it' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'not' is 'ont' which is located in the answer.
'coin' could be 'cent' (cent is a kind of coin) and 'cent' is found within the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'at' acts as a link.
Can you help me to learn more?
