Hello, I am deeply sorry for my mistake earlier; I did not notice that they were in sections. I think the best tip for PnC is to consider all possible combinations! Cheers, and good luck :)
In the first line, I am considering when X is the last question , and shifting the E around.
Then I consider X in the second last, and then the first in the stats section.
