U is the universal set for this question:
U = {2, 3, 6, 7, b, c, d, q, r, s, x, z}
A = {3, 2, 6, z, x, c, 7}
B = {s, 2, d, c, 7}
C = {s, b, r, 7}
(A \cup B) - C
Select from the options below all the elements in
Do not select any other elements, if there do not exist any elements to select, then select the option \"None\".
The marks are set so that selecting everything or nothing (if this is not the correct answer) will give you 0 marks and selecting all the correct elements and only the correct elements will give you all the marks.
Select one or more:
$\Box$ 3
$\Box$ 2
