Question

Let X and Y be the following sets: X = {3,8,9,12} Y = {8,9} What is the set X\Y?

Answer 1

Answer:

X\Y={3,12}

Explanation:

Given the sets X and Y below:

$\begin{gathered} X=\mleft\{3,8,9,12\mright\} \\ Y=\mleft\{8,9\mright\} \end{gathered}$

The set X\Y is the set of elements in X but not in Y.

Therefore:

$X\Y=\mleft\{3,12\mright\}$
