Question

let u={2, 3, 7, 9, 10, 13, 17, 20} and a={7, 9, 10, 13}. find the set a. a =

Explanation:

Step1: Define complement of set A

The complement \(A'\) contains all elements in universal set \(U\) that are not in set \(A\).

Step2: Identify elements in \(U\) not in \(A\)

Elements in \(U = \{2, 3, 7, 9, 10, 13, 17, 20\}\) not in \(A = \{7, 9, 10, 13\}\) are \(2, 3, 17, 20\).

Answer:

\(\{2, 3, 17, 20\}\)
