How many threads have you started on this type of question, Keannu? Why not try to get one problem sorted before you fire off another.
With so many threads, you might get slightly different responses from different pople in different threads, leading to further confusion.
In one of the other threads, one reason for rejecting 'would' in this sentence has been suggested. I have suggested that it is unhelpful to use percentages when talking of possibilities.
I am interested in this area of English Grammar, but I am afraid I am not going to look at any more of your posts on the subject. There is far too much likelihood of confusion.
