Find A^c

If A is a set, then the complement of A, denoted A^c, is the set consisting of all the elements in the universal set that are not in set A.

Let U = universal set

U = {a, b, c, d, e, f, g}

A = {e, f, g}

Find A^c.

Find A^c = {a, b, c, d}

I believe this to be right.

What a wonderful surprise. My textbook is not a set theory book. One day, I want to get deeper into this course.
