[quote]Have I won the lottery?[/quote]
I would change this to “Did I win the lottery?”
[quote]Is it possible in my imagination?[/quote]
I think this is a bit too abstract for a concept question – they need to be as simple as possible.
[quote]Is it probable that I win the lottery?[/quote]
I don’t think this conveys the meaning of the sentence. This question would be better for a first or second conditional sentence.
So, we need to think about the meaning of the two parts of the sentence:
[i]Did I win the lottery? (No)
Am I going to travel around the world?[/i] (No)
If we look at another example of the same structure:
“If I had done my homework, my teacher would be happy”.
…then the questions would be something like:
[i]Did I do my homework?
Is my teacher happy?[/i]
For your particular example, we could perhaps add another one that conveys the meaning of [u]that particular example[/u]:
[i]Do I want to travel around the world?[/i] (Yes)
…but this isn’t strictly necessary for the meaning of the structure itself.
Hope that helps.
