Suppose U{1,4,7,8,9,10,15,16,18} is the universal set and A= {1,8,9}. What is A
A is the set {1, 8, 9}.
A is a subset of the universal set U. It contains the elements 1, 8, and 9 from the universal set U.
To find the set A, we need to select the elements from the universal set U that are present in A.
In this case, the elements 1, 8, and 9 are present in set A. So, A = {1, 8, 9}.
