'Hope' is what you would LIKE to happen. 'Expect' is what you think will PROBABLY happen. If you are taking an exam, you might say: 'I hope I get an A grade. But I didn't work very hard, so, realistically, I expect I'll only get a B.' By the way, please don't write 'wanna', especially if you are asking strangers to help you. Native English speakers don't use this form in everyday writing. If you browse through the pages of this site, you will see that it is only learners of English who write like this. If a native English speaker wants someone to help them, we would say politely 'I'd like to know..' We would never write 'I wanna' in a request for help. It looks rude and childish.

You can only hope for something positive, but can expect anything at all whether positive or negative. To hope usually means to expect something positive, but sometimes the thing is so unlikely that you're not exactly expecting it but just wanting it to happen and recognizing that there may still be a chance.

"Expect" is usually about belief, while "hope" includes a strong element of desire. You may find the dictionary helpful. If you still have questions regarding a specific context, I'm happy to help. http://www.oxforddictionaries.com/us/definition/american_english/expect http://www.oxforddictionaries.com/us/definition/american_english/hope

Expect refers to a possible event that is probably going to occur. Hope is what one wishes will happen, but there is no element of probability involved. A common saying goes like this. "Hope for the best, but expect the worst."
