Consider U = {1, 2, 3, 4, ..., 21, 22) and A = {factors of 21},
List the elements of (a) A =
(b) A' =

Answer 1

The factors of 21 are 1, 3, 7, and 21. The complement of A, denoted by A', includes all the numbers in the universal set U that are not in A.

Step-by-step explanation:

(a) A = {1, 3, 7, 21}

(b) A' = {2, 4, 5, 6, 8, ..., 20, 22}
