Question

★ What is universal sets? Give one example.​

Answer 1

Answer:

For example, consider the single-digit numbers 1 through 9: If {1, 2, 3, 4, 5, 6, 7, 8, 9} is our larger set, then A and B are part of that set. Thus A and B are each a subset of this larger set, called the Universal Set. . All other sets are subsets of the universal set.

A universal set is a set which contains all the elements or objects of other sets, including its own elements. It is usually denoted by the symbol 'U'.

For example, consider the single-digit numbers 1 through 9: If {1, 2, 3, 4, 5, 6, 7, 8, 9} is our larger set, then A and B are part of that set. Thus A and B are each a subset of this larger set, called the Universal Set. All other sets are subsets of the universal set.
