会 means “will” in both sentences. Example: 1. 放心！我一定会去参加你的婚礼。Don’t worry, I’ll attend your wedding. 2. 下个月我会去北京一趟。I will go to Beijing next month. 3. 你会不会把这个秘密告诉她啊？Will you tell her the secret? Differences between 会不 and 不会 First of all, the meaning is pretty much the same but we use it in different way. Usually, we use不会 more often, and you can replace会不 by不会 all the time, for example: 1. A：如果你批评他，他会不高兴的。 B：如果你批评他，他不会高兴的。 2. A：上海人到北京可能会不习惯。 B：上海人到北京可能不会习惯。 3. A：你再不努力，这次考试会不及格的。 B：你再不努力，这次考试不会及格的。 Both sentences of each group have the same meaning. The subtle difference is that the A sentences emphasize the verb, such as “不高兴”，“不习惯”，“不及格”, and the B sentences emphasize the negative tone – “will NOT do something”. Moreover，in an overwhelming majority of sentences, you cannot replace不会by 会不, for example: 1. 北京人到上海大概不会有问题。Correct. 北京人到上海大概会不有问题。Wrong. 2. 你忘了他吧！他永远不会回来了。Correct. 你忘了他吧！他永远会不回来了。Wrong. 3. 不要再说了，我不会告诉你的。Correct. 不要再说了，我会不告诉你的。Wrong.

you can take 不习惯 as a phrase，不会有问题=no problem

thanks so much!

也许你可以分开来看，上海人|到|北京|可能会|不习惯。北京人|到|上海|大概|不会|有问题。不会有问题=没有问题 如果按照第一个句子的句式来说就是：北京人到上海 可能/大概 会习惯。

I am sorry I have typed the first sentence wrong, in my Chinese book is writen: 上海人到北京可能会不习惯。 And the second sentence is : 北京人到上海大概不会有问题。
