Aymen, I think you are right. These questions answers are not correct. Waiting for instructors' input.

Hello Aymen and André,

It is interesting to ponder a bit the questions currently in the quiz.
--------------------------------
Firstly, the complement of winning is indeed, as you have rightfully put it, everything that is not winning. When going over the questions
offered, I suggest reading them carefully. Nevertheless, your logic is correct, so concentrate on what the task requires us to point out.
--------------------------------
Secondly, I feel a small clarification concerning the whole numbers would help best.
We have three types of whole numbers:

1. negative, those strictly less than zero (x < 0)
2. zero itself, and
3. positive, those strictly bigger than zero (x > 0)
Now, when doing complements, you need to account for having 3 different types instead of 2.
Mind still, zero is neither positive nor negative. What does this imply for zero being non-positive / non-negative?
-------------------------------
Finally, a new redoing of the quiz is advisable - currently there should be no problems with the answers.
