    Simple negation of sentence

    All the participants of this course are IT majors or are math majors.

    The question asks to use basic logic laws.. and I am a bit confused on how to approach.

    Isn't it just

    Not all of the participants in this course are IT Majors or Math majors?

    or am I way off base?

    More thinking on this..

    What about

    It is not the case that all the participants of this course are IT majors or are math majors.

    That works right?

    Some of the participants of this course are not IT majors AND are not math majors.
    That is technically and formally correct.
    The negation of “All are…” is “Some are not…”
