Sets having the same cardinal number and same elements are called _________ sets.
equal
null
disjoint
Sets having the same cardinal number i.e. the same number of elements and the same elements are called equal sets.
Universal relation on a set A and universal set has same elements
The cardinality of a universal set, set A and set B are represented as n(U), n(A), n(B) respectively. Find the cardinality of the set which does not contain elements of set A and set B.
Universal relation on set A and Cartesian product A × A has the same elements
Find the cardinal number of the following sets :
(i)A1={−2,−1,1,3,5}
(ii)A2={x:x∈ N and 3 ≤x<7}
(iii)A3={p:p ∈ W and 2p−3 < 8}
(iv)A4={b:b∈Z and −7< 3b−1 ≤2} Cardinal~Number~of~set~:The number of elements in a set is called its Cardinal Number.
