Question

if A and B are any set a A is subset of B,then AnB​

Answer 1

2) If A and B are sets, then A is a subset of B if and only if, every element of A is also an element of B: A = {1,2,5,7} B = {1, 5} C = {1, 5} B is a subset of A; B is a subset of C. Another way of defining set equality is to say A = B if and only if A is a subset of B and B is a subset of A.
