$p$ : Every element in the empty set is greater than itself.
$\neg p$ : Some element in the empty set is smaller than or equals to itself.
I do not have the answers to this exercise, but it came out in my exams. I simply do not understand. There is nothing in an empty set! How can nothing be greater/equals/smaller/ to itself? If I had to choose an answer, it has to be $\neg p$ since nothing is equals to nothing...
What is the answer?
