Answer 1

Answer:

When talking about sets, it is fairly standard to use Capital Letters to represent the set, and lowercase letters to represent an element in that set. So for example, A is a set, and a is an element in A.

Answer 2

A set which contains no element is an empty or null set and we use { } or ∅ to denote this.Sets are commonly denoted with a capital letter like A = {1, 2, 3, 4}.
