How do you ask "Will you see your child next Sunday" in Chinese using verb not verb structure? What will be the difference between 你下个星期天会不会见你的孩子 and 你下个星期天会见不见你的孩子 ?

I am learning these sentences on Duolingo :) and was given the meaning of 你下个星期天会不会见你的孩子 as "Will you see your child next Sunday?". 

It would be great if anyone can explain how different would the other sentence (你下个星期天会见不见你的孩子) mean be from the first one.

And can these both sentences be equally written as 你下个星期天会见你的孩子吗?
the second has two verb. 會見and 不見(or maybe the sentence just ignore the conjunction.this is not formal)。
Here is correct grammar

你下个星期天见不见你的孩子


just take 会 away and the sentence will be perfect and have the same meaning as the former sentence.
or add conjunction

你下个星期天见或是不见你的孩子


And can these both sentences be equally written as 你下个星期天会见你的孩子吗?yes
