Ex1.4,12 State whether each of the following statement is true or false. Justify your answer. (i) {2, 3, 4, 5} and {3, 6} are disjoint sets. {2, 3, 4, 5} ∩ {3, 6} = {3} ≠ ∅ Since, there is a common element in both set. The given sets are not disjoint. False Ex 1.4,12 State whether each of the following statement is true or false. Justify your answer. (ii) {a, e, i, o, u } and {a, b, c, d} are disjoint sets. {a, e, i, o, u } ∩ {a, b, c, d} = {a} ≠ ∅ Since, there is a common element in both set. The given sets are not disjoint. False Ex 1.4,12 State whether each of the following statement is true or false. Justify your answer. (iii) {2, 6, 10, 14} and {3, 7, 11, 15} are disjoint sets. {2, 6, 10, 14} ∩ {3, 7, 11, 15} = ∅ Since, there is no common element in both set. Hence the pair of sets are disjoint True Ex 1.4,12 State whether each of the following statement is true or false. Justify your answer.
