If A = {3, 5, 7,

Answer :





(i) It is given in the question that,


A = {3, 5, 7, 9, 11}


And,




A∩B will give the members of set A and B that are common. Therefore,



(ii) It is given in the question that,


B = {7, 9, 11, 13}


And,


Intersection of two sets give the members of set that are common to both sets.


(iii) It is given in the question that,


A = {3, 5, 7, 9, 11}



And, D = {15, 17}


As there are no members of sets that are common, the intersection of A, B and C will be a null set.


(iv) It is given in the question that,


A = {3, 5, 7, 9, 11}


And,


Only 11 is common to sets A and C. Therefore,

= {11}


(v) It is given in the question that,


B = {7, 9, 11, 13}


And, D = {15, 17}


No member of set B is common with set D, Therefore intersection of B and D will be a null set.


(vi) It is given in the question that,


A = {3, 5, 7, 9, 11}


B = {7, 9, 11, 13}


And,


B U C will give all the members of both sets combined and not replicating the common members of the set. 

After that intersection of set A and B U C is calculated as the members that are common to these two sets.

= {7, 9, 11}


(vii) It is given in the question that,

A = {3, 5, 7, 9, 11}

And, D = {15, 17}


No member of the two sets is common, therefore the intersection of these two sets will be a null set.


(viii) It is given in the question that,


A = {3, 5, 7, 9, 11}


B = (7, 9, 11, 13}


And, D = {15, 17}




= {7, 9, 11}


(ix) It is given in the question that,


A = {3, 5, 7, 9, 11}


B = (7, 9, 11, 13}


And,




= {7, 9, 11}


(x) It is given in the question that,


A = {3, 5, 7, 9, 11}


B = (7, 9, 11, 13}



And, D = {15, 17}


Calculate A U B and B U C first and then intersection of these two sets is calculated.

= {7, 9, 11, 15}
