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

Question 2 :

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

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. From this we will get

A ∩ B  = A

If A ⊂ B,then show that A U B = B (use venn diagram)

Question 1 :

If A ⊂ B,then show that A U B = B (use venn diagram)

Solution :

Since A is the subset of B we have to draw a small circle A inside the large circle B.

A U B = B
