Do teachers want students to add their attempts on solving their own question in an email? I think this question holds for any kind of class, but if it actually makes a difference, it's a graduate level class.

Today I was drafting an email asking about uncertainties in a paper I'm supposed to do a presentation on.
When posing the questions, I added what I think is the solution to the question. 
However, I am not sure wether or not I should actually include the attempt of answering my question on my own. 

Pros


It shows that I actually tried to find a solution before writing them
It could make answering the email easy because they maybe don't have to explain much if I'm correct
Just asking the questions without any extra text (e.g the solution) makes the email itself seem blatant
It could reveal even more misunderstandings on my part, increasing the value of their answer


Cons


It just bloats the email, maybe making it less appealing to read and answer 
They might not care what I think because they "have to" write their own answer anyway
(If the answer is way off, it might throw a bad light on me)


Neutral


Might depend on the person I'm asking


If it depends on the person I'm asking, how would I actually recognize wether he/she wants me to add my thoughts or not? 
Therefore, I am in confusion wether or not to add my attempts to the email or not.
Yes absolutely include it. That's the only way for the instructor to see where the gaps in your knowledge are. If you think it makes the email too long, then put a concise summary at the top and then the details below.

Edit: consider also that in the above post, you attempted to answer your own question. Look how much context that gave to the question. Imagine if you'd posted the title and the bolded statement only. We would not have understood your thought process. You might not have received many useful answers, just comments asking you to clarify what you were asking
