use of will/would

[Hardwork]

1) "would" after wish expresses a strong desire.what does this mean please explain me with egs.
2)"will" is used to express characteristic habit
eg: She will sit for hours listening to wireless.
I'm confused her for habitual action we use simple present , right so when should we actually use will to express characteristic habit.
3)Will is used to express assumption or probability.What does this means, please explain me with egs.

1. I wish you would be quiet. I am trying to read.

2. That example is really no different from the simple present version.

3. Basketball player LeBron James will pick Miami. Just wait and see. - I am not stating a definite truth. I am predicting an outcome.
