Question

if a,b,c are non empty sets then a-(b-c)=​

Answer 1

Answer:

Let A,B,C be any sets.

If we take intersection of sets, it should be distributive over union of sets.

Let's take union of B and C i.e. B∪C and then intersect with A.

∴ Finally we get A∩(B∪C), which is same as union of intersection of A,B and A,C.

i.e. A∩(B∪C)=(A∩B)∪(A∩C)

Hence, option A is correct.
