Question

if A ={1,2,3,4}and B={2,4,6,8} then prove that (A Union B ) - (A intersection B)​

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)
