hi good morning how are you have a nice day

Answer 2

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.
