Question

A and B are the two sets.such that A subset B .Draw the venn diagram for A union B

Answer 1

Make a big circle. We will call it B.

2- Make a small circle at the center of B. We will call it A.

3- Shadow the area that is inside of A and outside of B at the same time. The shadowed area should look like a two-dimensional doughnut. That area is B\A.

B\A is the set of all elements of B that are not A’s, that is, the intersection of B with the complementary of A.
