Mathematics Exercise: Q. State which of the following sets are null sets and which are singleton sets. i) W=Set of the vowels in the word 'book'. ii) P={x:x is a prime number less than 2} Day-26 Activity:26 (Set) Equal set: Example:E= {FILE} F= {LIFE} Here, n(E) = 4 and n (F) = 4 Also, the sets E and F have same elements. So they are called equal sets. Exercise: Q. List the elements of the given sets. Are they equal? A = {2, 3, 5, 7, 11}, B = {Prime number less than 12} Day - 27 Activity:27 (Set) Equivalent set: The sets are said to be equivalent if they contain the same number of elements. Example: A = {1, 2, 3, 4} B = {a, b, c, d} Here, n(A) = 4 and n(B = 4) contain same number of elements So, set A and B are equivalent sets. Exercise: Q. A = {letters of the word 'LOVE'} and B = {0, 1, 2, 3} Are they equivalent? Day -28 Activity:28 (Set) Overlapping sets wo sets are called overlapping if they have at least one element in common. Examples: A = {a, e, i, o, u} B = {u, v, w, x} A a v e ou x i w Common element is 'u' . So, it is overlapping set. --51--

Disjoint set: P Class-6 Two sets are called disjoint sets if they 1 Q have no element is common. 56 78 Example: P = {1, 2, 3, 4} 2 Q = {5, 6, 7, 8} 3 4 Since there is no element in common, so it is disjoint set. Exercise: Q. If A = {a, b, c, d, e} and B = {d, e, f, g, h} then examine the relation overlapping or disjoint with diagram. Day - 29 Activity: 29 (Set)  Listing the elements from figure.
