F SET A HAS {1, 3, 5, 7}, SET B = {3, 7, 9, 11}, WHAT IS THE INTERSECTION OF A and B, and THE CARDINALITY OF THE SET?
Answers
Step-by-step explanation:
Given sets are A={1,3,5,7} and B={3,7,9,11}
Now ,AnB ={1,3,5,7}n{3,7,9,11}={3,7}
The intersection of the sets A and B ={3,7}
The number of elements in AnB=2
The cardinal number of AnB=2
Therefore,n(AnB)=2
Therefore,n(AnB)=2A intersection B= The set contains all the common elements in both A and B and it is denoted by AnB.
Therefore,n(AnB)=2A intersection B= The set contains all the common elements in both A and B and it is denoted by AnB.Cardinal number of a set:- The number of all distinct elements in a set is called the Cardinal numbers of the given set.
Therefore,n(AnB)=2A intersection B= The set contains all the common elements in both A and B and it is denoted by AnB.Cardinal number of a set:- The number of all distinct elements in a set is called the Cardinal numbers of the given set.The cardinal number of a set A is denoted by n(A).
