Question

Let and A = (k, 1, n, 0) Use the roster method to write the set A

Answer 1

So,

Given that:

$\begin{gathered} U=\mleft\lbrace j,k,l,m,n,o,p\mright\rbrace \\ A=\mleft\lbrace k,l,n,o\mright\rbrace \end{gathered}$

We want to find the set:

$A^{\prime}$

A' is the set that excludes the elements of the set A.

As we can see, the set A doesn't have the values:

$k,l,n,o$

So it should have the other values that the set U actually has. These are:

$A^{\prime}=\mleft\lbrace j,m,p\mright\rbrace$
