Explanation Given information: Given, to explain the reason for the statement { 2 } ∉ { 1 , 2 , 3 } . Calculation: Any term with {} represents set and without {} represents just elements. The relation between elements and set is given by ∈ (belongs) whereas the relation between a set and another is given by ⊆ (subset) For example, a ∈ { a , b , c } and { a } ⊆ To determine (b) To explain: To explain why 1 ⊄ _ { 1 , 2 , 3 } . To determine (c) To explain: To explain if the set { 1 , { 1 } } have one or two elements.
