### Cardinal Properties of Sets (advance math)

Cardinal Properties of Sets   Cardinal Properties of Sets: We have already learnt about the union, intersection and difference of sets. Now, we will go through some practical problems on sets related to everyday life.   If A and B are finite sets, then • n(A ∪ B) = n(A) + n(B) – n(A ∩ B)…

### Cardinal Number of a Set (advance math)

Cardinal Number of a Set   What is the cardinal number of a set? The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A) and read as ‘the number of elements of the set’. For example: (i) Set A = {2, 4, 5, 9, 15} has…

### Problems on Operation on Sets (advance math)

Problems on Operation on Sets Solved problems on operation on sets are given below to get a fair idea how to find the union and intersection of two or more sets.   We know, the union of sets is a set which contains all the elements in those sets and intersection of sets is a set which…

### Problems on Complement of a Set (advance math)

Problems on Complement of a Set   Solved problems on complement of a set are given below to get a fair idea how to find the complement of two or more sets. We know, when U be the universal set and A is a subset of U. Then the complement of A is the set…

### Difference of Two Sets (advance math)

Difference of Two Sets   How to find the difference of two sets? If A and B are two sets, then their difference is given by A – B or B – A.  • If A = {2, 3, 4} and B = {4, 5, 6}  A – B means elements of A which are not…

### Problems on Intersection of Sets (advance math)

Problems on Intersection of Sets   Solved problems on intersection of sets are given below to get a fair idea how to find the intersection of two or more sets. We know, the intersection of two or more sets is a set which contains all the elements that are common in those sets.   Solved problems on…

### Intersection of Sets (advance math)

Intersection of Sets   Definition of Intersection of Sets: Intersection of two given sets is the largest set which contains all the elements that are common to both the sets. To find the intersection of two given sets A and B is a set which consists of all the elements which are common to both…

### Union of Sets (advance math)

Union of Sets   Definition of Union of Sets: Union of two given sets is the smallest set which contains all the elements of both the sets. To find the union of two given sets A and B is a set which consists of all the elements of A and all the elements of B…
