(*) a probabilidade, improbabilidade ou impossibilidade "vê-se" na CONDIÇÃO, não no seu resultado

impossible conditions are impossible, because you can't change the past (*)
after WILL or WOULD, we use the plain infinitive [without(sem)'to']
will ='ll ; would ='d ; will not = won't
' were ' is normally used in conditional clauses instead of (em vez de) ' was '
you can use ' could ' and ' might ' instead of ' would '

examples:

situation: conversation between two friends (A and B) at a football stadium...
