Question

if A is a subset of B then 1. a belongs to A = a not belongs to B 2. a belongs to A= A = a belongs to B​

Answer 1

Answer:

Step-by-step explanation:

A={1,A}

B={2,A}

Sets A and B have two elements, one of which is set A.

subsets of A: {}, {1},{A},{1,A}

= {},{1},{A},A

subsets of B: {}, {2},{A},{2,A}

A is a subset of itself, and not a subset of set B.

The set of the set A, which is {A}, is a subset of set A and a subset of set B
