Why the examiner added "exactly" in part (f) and (g) but not in (e)?
This makes me think that part (e) is about Jess winning after 2 or more spins!!
But the marking scheme shows that the examiner only means Jess winning after exactly 2 spins
Am I thinking too much?

Thanks in advance!!

How can a question be urgent on Christmas eve?!

I think they're using the word exactly to try and catch people out, because it's the same method for e,f,g.

I'd guess that-
"win after 2 spins" = win on spin 1 OR win on spin 2, whereas
"win after exactly 2 spins" = win on spin 2 ONLY
