Find (AnC)' using roster method.

U = {1, 2, 3, 4, 5, 6, 7, 8}

A = {1, 3, 4, 8}

C= {1, 2, 4, 5, 8}

correct: 0

Find (AnC) using roster method.

To find \((A \cap C)'\) using the roster method, we will follow these steps:

### Step 1: Find the intersection \(A \cap C\)

The intersection of sets \(A\) and \(C\), denoted as \(A \cap C\), contains all the elements that are present in both sets.

Given:
- \(A = \{1, 3, 4, 8\}\)
- \(C = \{1, 2, 4, 5, 8\}\)

Now, let's find \(A \cap C\):
- Elements common in both \(A\) and \(C\) are: \(\{1, 4, 8\}\)

So, \(A \cap C = \{1, 4, 8\}\).

### Step 2: Find the complement of \(A \cap C\), denoted as \((A \cap C)'\)

The complement of a set \(X\) (denoted as \(X'\)) consists of all the elements in the universal set \(U\) that are not in \(X\).

Given:
- Universal set \(U = \{1, 2, 3, 4, 5, 6, 7, 8\}\)
- \(A \cap C = \{1, 4, 8\}\)

Now, find \((A \cap C)'\):

\((A \cap C)' = U - (A \cap C) = \{2, 3, 5, 6, 7\}\).

### Answer:
\[
(A \cap C)' = \{2, 3, 5, 6, 7\}
\]
