Question

If A={1,2,3,4} , B={5,7,9} C={2,4,6} Find CXA and draw their graph.​

Answer 1

Answer:

Given, A={1,2,3,4,5},B={2,4,6,8} and C={3,4,5,6}

For the LHS:

Union of two sets will have the elements of both sets.

So, B∪C={2,3,4,5,6,8} 

A−(B∪C) will have elements of A which are not in (B∪C)

So, A−(B∪C)={1} 1)

For the RHS:

A−B will have elements of A which are not in B.

So, A−B={1,3,5}  

A−C will have elements of A which are not in C.

So, A−C={1,2}  

Intersection of two sets has the common elements of both the sets. 

⇒(A−B)∩(A−C)={1} (2)

From (1) and (2), we have

A−(B∪C)=(A−B)∩(A−C)

Hence, the given expression is true.
