Find A U B
Consider a={1,3,5} and b={2,4,6}
Find A n B
Let A={1,2,3,4,5,6} and b={2,4,6,8}
What is the cardinaality of A n b ?
Solution
1 ) Given that
A = { 1 , 3 , 5 } and B = { 2 ,4 ,6 }
We know that
A U B = Total elements present in A and B
Hence ,
A U B = { 1 , 2 , 3 , 4 , 5 , 6 }
2 ) Given that
A = { 1 , 3 , 5 } and B = { 2 ,4 ,6 }
We know that
A B = Common elements present in A and B
Hence ,
A B = { 0 } [ Since ,there is no common elements in A and B ]
3 ) A = {1,2,3,4,5,6} and B ={2,4,6,8}
A B = { 2 , 4 , 6 }
We know that
The cardinality of a set is a measure of the \"number of elements of the set \"
Hence ,
Number of elements in A B = 3
Therefore ,
Cardinatity of A B = 3
