SOLUTION: I am working with sets. My sets are as follows:
U = {a, b, c, d, e, f, g, h, i, j, k, r, t, y}
A = {b, i, r, t, h, d, a, y}
B = {c, a, k, e}
C = {c, a, r, d}

Question 555875: I am working with sets. My sets are as follows:
U = {a, b, c, d, e, f, g, h, i, j, k, r, t, y}
A = {b, i, r, t, h, d, a, y}
B = {c, a, k, e}
C = {c, a, r, d}
Problem #1 A' =
Problem #2 C' (upsidedown cup shape) A
In reference to these problems what does the apostrophe ( ' ) mean.

, more correctly denoted
, means the complement of the set, or in this case, since the Universe set,
, is defined,
denotes the absolute complement of the set
. The absolute complement of a set is the set of elements contained in
but NOT in
.
Your "upside down cup" is the intersection symbol and denotes the set of elements that are in both sets. You first must find the complement of
and then the intersection of that set with
