Question

2. If A B 1 , then find A B + and A B\ (use Venn diagram).

Answer 1

QUESTION:
If A ⊂ B, then find A ∩ B and A \ B (use venn diagram)

Venn diagram :
A Venn diagram is a closed figure used to denote a set. Points within such a closed figure represent the elements of the set. Venn diagrams can be used to represent the relationship between sets. That Universal set U is usually represented by a rectangle.

Intersection of two sets :
The intersection of the sets a and b is the set of all the elements which belong to both A and B. It is denoted by A ∩ B (“ A intersection B”).

SOLUTION :
Since, A is the subset of B we have to draw a small circle A inside the large circle B.
A ∩ B means we have to shade common part of A and B.
A ∩ B = A

Venn diagram is in the attachment.
