Answer :

A = {1, 2, 3, 4, 5 …}


B = {2, 4, 6, 8 …}


C = {1, 3, 5, 7 …}


D = {3, 5, 7, 11 …}


We know that the intersection of sets A and B is the set of all elements which are common to A and B.


A B = {1, 2, 3, 4, 5 …} {2, 4, 6, 8 …} = {2, 4, 6 …} = Even natural number


A C = {1, 2, 3, 4, 5 …} {1, 3, 5, 7 …} = {1, 3, 5 …} = Odd natural number


A D = {1, 2, 3, 4, 5 …} {3, 5, 7, 11 …} = {3, 5, 7 …} = Prime number


B C = {2, 4, 6, 8 …} {1, 3, 5, 7 …} = ϕ


B D = {2, 4, 6, 8 …} {3, 5, 7, 11 …} = ϕ


C D = {1, 3, 5, 7 …} {3, 5, 7, 11 …} = {3, 5, 7 …} = Prime number
